There is no doubt that the stem cell field is generating a great deal of excitement and hope. Efforts are underway across the globe to find cures for incurable diseases. Yet despite these exciting developments, only a limited number of procedures are approved for routine therapy.
A spinal cord injury
Bone marrow transplantation, which has been performed for cancers and blood disorders for several decades, is one for the few universally approved and routinely practiced forms of stem cells therapy.
On 31 May 2019, Health24 published an article stating that stem cell treatment had improved the quality of life of a rugby player who sustained a spinal cord injury. Rugby injuries are often low velocity injuries and in many cases, the injuries that are sustained are incomplete.
The implication is that recovery is possible, to a greater or lesser degree, with follow up rehabilitation. To date, despite numerous research efforts and clinical trials, there is virtually no evidence that stem cells can cure spinal cord injury. Several factors are critical when assessing a case such as the one mentioned above. What was the origin of the cells used? How were they administered? Was the patient walking before the stem cells were administered?
Equally important, did the administration of the stem cells comply with the laws of the country, and since this is an unproven therapy, should it have been considered as a clinical trial? In the case of the latter, a number of critical steps would have needed to be followed.
While not wanting to detract from the great joy of seeing someone recover from a debilitating injury, accurate reporting is important if one is to ensure that vulnerable patients are not emotionally and financially exploited. There is regrettably a global trend involving “stem cell clinics” that seeks to treat a range of diseases using unproven stem cell therapies. Propagating the idea that there is a direct causal relationship between the administration of stem cells and a positive outcome, without considering all of the facts, may be misleading and may prompt other vulnerable patients to undertake similar unproven therapies.
It is therefore the responsibility of the person reporting the story to do so in a manner that is objective, and to avoid implicating direct causality unless this can be proven. Evidence-based and ethical marketing is also important in order to avoid misleading vulnerable patients and their families. An advertisement, currently running on one of the local radio stations, indicates that the future use of stored stem cells will “overcome my diabetes” and “treat my autism”.
While there is ongoing research in both of these areas, and many more, there is no guarantee that stem cells will be able to be used to treat these conditions in the future. Given the extent of the emotional involvement around matters pertaining to children, potential customers might be made to believe that by banking their newborn’s stem cells, “the child you have today will be protected tomorrow”.
While there is the potential that stored stem cells might well be used in the future for bone marrow transplantation or for regenerative medicine purposes, this information should be convened objectively, which includes placing the possibility of a future cure into perspective relative to the evidence currently available. Why is it important to proceed cautiously with new treatments that have the potential to cure previously incurable diseases?
One important reason is highlighted in a recent court decision in the US. As noted by the International Society for Cell and Gene Therapy, “this ruling an important step towards the regulation of an industry that has eluded regulatory oversight for many years, causing substantial financial, and in many cases, physical harm to patients through direct-to-consumer advertising of unproven and poorly tested “stem cell” treatments”.
In other words, as long as a treatment that eludes regulatory oversight does no harm, financial loss will be the only issue that needs to be contended with. However, in the case mentioned above, four patients were blinded by stem cells administered directly into their eye. And there are many more examples of cases in which patients have been harmed by unproven “stem-cell” therapies. The argument is often put forward that the use of the patient’s own stem cells does not require regulatory oversight.
Exploitation and possible harm
This is a complex matter, particularly since the cells are often processed in one form or another before being re-administered to the patients, which would qualify them as being “minimally-manipulated”. While there is no specific legislation governing this matter in South Africa, international best practice requires regulatory oversight with the use of such a product. To conclude, evidence-based and ethical reporting and marketing are necessary if patients are to benefit from the great strides being made in the stem cell field.
Not to do so exposes vulnerable people to exploitation and possible harm. It is critical that the South African Government provides an appropriate regulatory framework to allow patients to benefit from advances in the stem cell field while at the same time protecting them from exploitation and harm. This will also promote much needed research, investment and entrepreneurship in the stem cell field for the benefit of all of the people of our country.

The University of Cape Town, in partnership with the ACGT, DIPLOMICS and Stellenbosch University, hosted the Trans-Proteomic Pipeline (TPP) workshop which ran from the 21sttill the 22ndof March 2019.
The workshop, which followed the HUPO-PSI meeting, held from the 18thtill the 20thof March 2019, was facilitated by Dr Eric Deutsch and Mr Luis Mendoza from the Institute of Systems Biology (Seattle-USA). Dr Deutsch is a lead designer for the Systems Biology Experimental Management System. He is the Chair of the HUPO-PSI and is one of the leaders of the TPP project- that aims to provide a free and open-source suite of tools for the processing and analysis of proteomic tandem mass spectrometry data.
Mr Mendoza is a senior software engineer at the Institute for Systems Biology. He has been a main contributor to the development of the TPP for the past 14 years.
The two-day workshop was attended by 35 delegates from Universities in the Western Cape region (University of Cape Town, Stellenbosch University, University of the Western Cape and Cape Peninsula University of Technology) as well as delegates from other provinces (Gauteng and KZN).
The ACGT partnership was represented by four delegates at the workshop. The ACGT representatives hailed from the Council for Scientific and Industrial Research (Dr Previn Naiker and Dr Ireshyn Govender), the University of the Witwatersrand (Ms Genevieve Mezoh), and the University of Pretoria (Ms Denise Wilson). The delegates from the ACGT partnership are expected to transfer the knowledge gained from the TPP workshop by training their fellow unit/lab students/colleagues. A week after the workshop, Ms Denise Wilson reported that she was in the process of working with the Centre for Bioinformatics and Computational Biology (CBCB) at the University of Pretoria to install the TPP pipeline for command line execution on their Linux servers.
The next proteomics training workshop will be in November 2019 and it will focus on the open-source software package Skyline, data analysis and SWATH. Information regarding this workshop will be disseminated at a later stage.

Sanushka Naidoo, associate professor in the Department of Biochemistry, Genetics and Microbiology at the University of Pretoria (UP), was recently elected chairperson of the Next Einstein Forum’s (NEF) Community of Scientists programme. The NEF is a joint initiative of the Robert Bosch Stiftung Foundation and the African Institute for Mathematical Sciences (AIMS), which has centres in South Africa, Ghana, Senegal, Cameroon and Tanzania.
“The next Einstein could be African,” Prof Naidoo said. “It is up to us to find and nurture such upcoming generations of Einsteins. I am looking forward to presenting our NEF Community of Scientists vision and progress at the next World Economic Forum.”
The NEF provides opportunities for some of the brightest minds in Africa to look at the most persistent problems experienced on the continent and apply technology, engineering and mathematics as well as the social sciences to come up with possible solutions.
“I am honoured and humbled to be elected by such accomplished young scientists,” Prof Naidoo added. “I feel inspired and motivated to lead the community of scientists one step closer to achieving our vision.”
The KwaZulu-Natal-born professor’s vast experience in the field of plant biotechnology will stand her in good stead in her new position. She heads the Eucalyptus and Pine Pathogen Interactions group and works closely with the Forest Molecular Genetics Programme, part of the world-renowned Forestry and Agricultural Biotechnology Institute (FABI) at UP. She is also a committee member of Future Africa at the University of Pretoria.
She has also published more than 30 papers in international peer-reviewed journals, was awarded a Y-rating by the South African National Research Foundation (2015-2020), a Mellon Foundation Mentoring scholarship for her doctoral studies in plant biotechnology, and serves as president of the South African Genetics Society (2017-2020).
The professor’s research interests include genetics, plant biotechnology as well as cell and environmental biology, and she currently teaches molecular genetics at UP. She is the main supervisor to two postdoctoral researchers (Dr Caryn Oates and Dr Erik Visser), two PhD students (Ms Lorraine Mhoswa and Mr Demissew Teshome), one MSc student (Ms Shannon Flemington) and two honours students (Shae Swanepoel and Kgopotso Pakwako).
Prof Naidoo first became involved with the NEF when she was awarded an NEF Fellowship (2017-2019), a programme that recognises the contribution of top young scientists and emerging leaders in Africa, and gives them the opportunity to grow their careers and present their work at the global NEF Spotlight Sessions. As part of the programme, fellows are expected to participate in national and continental policy formulation, cross-cutting research and innovation activities, lead public engagement around science and technology in Africa, and provide mentorship to early-career scientists and students.
During her tenure at the NEF, Prof Naidoo plans to focus on breaking down some of the barriers young African scientists face, such as lack of infrastructure, collaborative networks and resources. She says it’s important for people in leadership positions to remain positive and persevere despite challenges. Over the next two years, the NEF aims to strengthen ties with the community of scientists in order to offer them a strong support network that enables them to achieve their goals. The organisation also intends to build capacity and empower African scientists so they’re able to make use of international opportunities.
Prof Naidoo’s love affair with nature started at a young age. Her parents – both teachers – have always encouraged her to ask questions about the world around her. Her interest in plant science was piqued by a science teacher who encouraged learners to establish a nature club at school.
“We built a pond on the school premises and we watched a whole ecosystem develop over time. This became a teaching tool for our biology classes, and we were fascinated with how organisms depend on each other for survival.”
After matriculating, she enrolled for a degree in Cell and Environmental Biology at the University of KwaZulu-Natal (UKZN), and became interested in plant genetics. She completed her honours at UKZN before obtaining an MSc degree in plant biotechnology at the University of Stellenbosch, and her PhD at UP.
Her current research focuses on mechanisms that can confer broad-spectrum, long-lasting resistance by dissecting gene families and responses to pests and pathogens. With the development of new technologies, novel genetically modified crops are poised to increase yield and protect against pests and pathogens under harsh African climates.
When she’s not among the trees or in the lab, she loves spending time with her husband Tyrrell, her three children Tristan (15), Sunera (8) and Telana (7), and Dakota Rouge, whom she describes as “a beautiful King Charles Cavalier spaniel”. She also enjoys writing poetry and reading motivational books on leadership.
About 40% of the NEF fellows are women, and Prof Naidoo is quick to remind anyone that women have been integral to important scientific discoveries over the ages.
“I think of physicist Marie Curie, cytogeneticist Barbara McClintock and biochemist Jennifer Doudna as exemplars of women who have made impactful scientific breakthroughs. There are other types of contributions by women scientists that deserve attention too, such as Kenyan scientist Wangari Muta Maathai, who was the first African woman to win a Nobel Peace Prize for her efforts to combat deforestation. I believe that women will continue to break through glass ceilings and shape the future because of their passion and commitment to changing lives for the better.”

The 2019 Metabolomics symposium was held at the Innovation Hub from 11-12th March 2019. This symposium was aimed at principal investigators, postgraduate and PhD students currently performing or planning to work in the metabolomics field. This event was an opportunity for both local and international metabolomics researchers to share their findings, to network and identify synergies so as to foster further collaboration amongst metabolomics researchers within SA and across Europe. This symposium was mainly a platform to officially launch Metabolomics South Africa (MSA). MSA is a non-profit organization seen as an opportunity to promote and improve the profile of metabolomics research and technology in South Africa, foster networking, training, capacity building, information sharing, mentoring, career opportunities, leadership training and professional development. The symposium was a first official event hosted by MSA with the assistance of its partner, the ACGT.
The first day of the symposium was themed “Metabolomics, where are we?”. Topics discussed throughout the day included the overview of metabolomics in South Africa, good metabolomics data, role of metabolomics in health sciences, lipidomics and plant metabolomics. The discussions on the second day of the symposium were under the theme “Metabolomics, informatics, statistics and applications” and covered topics such as metabolomics networks, statistical models, NMR metabolomics and lipidomic profiling. At the end of each day, attempts were made to finish off with round table discussions to address burning issues or questions on the day’s talks as well as other issues regarding to metabolomics or MSA.
It is worth mentioning several key speakers that participated and contributed to the symposium. The speakers mentioned below are all key contributors to the field of Metabolomics and we are thankful that they shared their work and experiences.

The Africa Centre for Gene Technologies (ACGT), in conjunction with the University of Zurich, University of Pretoria and the Agricultural Research Council, hosted a successful whole transcriptome sequencing (RNA sequencing or RNASeq) data analysis workshop for researchers from the 1st to the 8th of February 2019. The workshop was held at the Hatfield campus of the University of Pretoria.
RNA sequencing aims to unravel the sum of all transcripts in an organism at any given moment in time and can give important clues to changes occurring in an organism following a variety of environmental cues or life stage transitions. The workshop started with two days of introductory courses in Linux and R. The introductory courses were facilitated by Professor Fourie Joubert from the University of Pretoria and Dr Rian Pierneef from the Agricultural Research Council. These courses offered the delegates basic command line skills needed to manipulate RNA sequencing data.
The two days of introductory courses were followed by a four-day interactive and hands-on RNA Sequencing workshop. The workshop was facilitated by renowned experts and academics from the Institute of Molecular Life Sciences at the University of Zurich in Switzerland: Professor Mark Robinson and Dr Simone Tiberi. Professor Mark Robinson is involved in research that applies statistical methods and data science to experimental data with biological applications within the context of genomics data types. Dr Simone Tiberi is a post-doctoral research fellow who is working on the development of cutting-edge statistical methods in bioinformatics, mostly for bulk and single-cell RNASeq data.
The workshop covered theoretical aspects of RNA sequencing such as new technologies, applications, experimental design, batch effects, dimension reduction, clustering, quality control, limma, normalization quantification and differential expression, among other things. There were also one-on-one sessions with delegates to address their specific queries or to clarify any issues that may have arisen. The delegates hailed mostly from the ACGT partner institutions; University of Pretoria, University of Johannesburg, University of the Witwatersrand and the Agricultural Research Council. The feedback from the delegates was very positive in how the course was designed, organized and conducted. The ACGT is hopeful that the course will be beneficial to all the researchers that came to the workshop and to those that work close with them.
The ACGT and all of its partners would like to extend enormous gratitude to Professor Mark Robinson, Dr Simone Tiberi, Dr Rian Pierneef and Professor Fourie Joubert for sharing their time and expertise with the attendees. The ACGT would also like to thank Professor Fourie Joubert and Mrs Itseng Malao for all of their assistance in organizing this event. The Centre wishes all the participants the best of luck with applying their newly learned skill to their work.

Wageningen University and Research (WUR) is a higher institute of learning based in the Netherlands that specialises in the areas of food and food production, living environment, and health, lifestyle and livelihood. WUR opens its doors to the international community and offers short courses in the areas that the institution specialises in. One such course came to ACGT’s attention as it related closely to what the ACGT as an organization is mandated to achieve and the projects that the ACGT is involved in.
The institution offers a short course (three weeks) called “Facilitating Multi-Stakeholder Partnerships to Foster Sustainable Food Systems”. This course was deemed quite applicable for ACGT staff as the Centre is itself a multiple stakeholder partnership mandated to build capacity in the area of advanced biotechnology for five institutions (three universities and two science councils).
The ACGT found it necessary to send one of its staff members, Mr Thabo Khoza – Liaison Scientist at ACGT, to the Netherlands to attend this three-week course in order to enable ACGT staff to be better multi-stakeholder facilitators. The course ran from the 22nd of October 2018 till the 9th of November 2018.
The course took the participants on a journey of (1) establishing what sort of a multiple stakeholder partnerships (MSPs) are required for different projects and needs, (2) who to involve in such MSPs, (3) how to design the required MSP, and (4) how to facilitate the MSP to yield desired outcomes. While all four mentioned steps are crucial in ending up with an MSP that works, step 4 would require the most effort and resources from the MSP facilitator. This effort is especially highlighted when dealing with different stakeholders who have different interests and varying levels of influence. The course gave the participants a number of tools to use in the facilitation process to make sure that the MSP is a success. Each tool would be chosen based on the stakeholders involved as well as on the type of MSP that has been created.
The course had theory and practical components to it. The participants were divided into groups at the beginning of the course and they were tasked to come up with a problem (project) that would require an intervention of an MSP. Throughout the course, the participants would then have to apply what they were learning in their project. At different levels of formulating their MSPs, the participants would give presentations on how they applied what they have learned during their projects.
The participants were also given a real life problem to design an MSP on. This scenario took the participants to Friesland where they had to design a pathway of creating a cooperative that would address the biodiversity problems that are faced in the Friesland region. The participants had to interview farmers, government officials, business owners, nature reserve experts, activists and civil society. The participants then, based on the interviews and what they had been learning at Wageningen, created a roadmap for establishing this cooperative. This roadmap was presented to the community of Friesland where all the stakeholders were invited. The presentation took about two hours with Mr Khoza being the master of ceremonies, together with a fellow participant from Indonesia. The MSP design suggested by the course participants was well received with the project lead promising to use the suggested roadmap.
The course came to an end with participants giving presentations based on their individual MSP that they want to set up when returning to their home countries. The course facilitators as well as the course participants gave suggestions at the end of each presentation.
The course was also a great platform for networking as it was attended by individuals from 14 different countries representing different sectors and expertise such as government and policy makers, scientists and NGOs. The participants have an active network and are actively looking for opportunities for collaboration.
The ACGT hopes that Mr Khoza will put into practice the knowledge he acquired at Wageningen University and Research especially in creating new initiatives for the ACGT community, such as the Proteomics Society for South Africa.

The second Regional Plant Biotechnology Forum for 2018, co-hosted by the ACGT and the University of Johannesburg, centered around plant-pathogen interactions; a particular area of interest for numerous researchers in the partnership and beyond. As is appropriate in the “-omics” and systems biology era, the theme for the forum was “Advances in Plant Defense Responses: Towards Plant-Pathogen System Perspectives”. The topic was deliberately chosen to provide a platform for those who aim to unravel such responses from a wider systems perspective.
The wide variety of presentations, most with a focus on genome-wide approaches to deciphering plant defence systems, managed to attract in excess of 60 delegates from a range of universities, science councils (the majority being from ACGT partner institutions) as well as funders. The keynote speaker for the event was Dr Naadirah Moola, a researcher associated with both the University of Cape Town and the University of Ghent, Belgium. The title of her address was “A cereal killer’s killer: chitosan and plant defence”. Her address was followed by ten additional presentations, mostly from researchers associated with the Universities of Johannesburg and Pretoria. The presentations included studies utilizing technologies including transcriptomics, proteomics, multi-platform metabolomics, as well as combinations of the above. In addition, classical biochemical approaches were also utilised in addressing the research questions at hand.
The forum provided an excellent networking opportunity for researchers active in this field and exposed them to different approaches to elucidating plant-pathogen interactions in different systems.
The ACGT would like to sincerely thank the organizing team at ACGT (Thabo Khoza, Molati Nonyane and Itseng Malao), as well as UJ (Dr Farhahna Allie, Dr Ian Dubery and Dr Fidele Tugizimana).

Two University of Pretoria (UP) academics have received prestigious A1 ratings by the National Research Foundation (NRF) for 2018, bringing the number of UP scientists rated in the A category to 14.
Prof. Don Cowan, Director of the Centre for Microbial Ecology and Genomics, has received an A1 rating, up from his previous A2 rating, while Prof. Mike Wingfield, founding director of UP’s Forestry And Biotechnology Institute (FABI), had his A1 rating renewed.
An NRF rating is a measure of the quality of a researcher, based on peer reviews of their publication performance and impact, including international recognition. A researcher in the A-rated category is recognised by all reviewers as a leading scholar in his/her field internationally for the high quality and wide impact – beyond a narrow field of specialisation – of his/her recent research outputs.
Prof. Cowan established the Centre for Microbial Ecology and Genomics in 2013. The Centre works on various aspects of soil microbial ecology, with a particular focus on hot and cold desert ecosystems. The team uses the latest metagenomic and bioinformatics methods to investigate the structure, function, adaptation and resilience of soil microbial communities, to further understanding of their roles in soil health, plant productivity and the provision of genetic resources. “I am absolutely delighted with the NRF rating result,” Prof. Cowan says. “One of the wonderful elements of academia is that it is possible to be rewarded for working on something about which one is passionate. But this is not a solo effort: I must also gratefully acknowledge and sincerely thank all those who have played their part, whether big or small, in this wonderful result: my research collaborators, my postdocs and students, my friends and my colleagues, and my wife.”
Prof. Wingfield’s research interests are focused on the broad area of forest health, particularly those caused by insect pests and pathogens of trees, and their patterns of global movement. Together with his colleagues and collaborators, the research team applies a wide range of biotechnology tools in order to better understand the biology and epidemiology of tree pests, and reduce the dramatic impact they are having globally. Asked about once again receiving an A1 NRF rating, Prof. Wingfield said, “This award belongs as much to me as it does to the amazing FABI team, including a wonderful group of colleagues, students and collaborators globally. I hope they will enjoy the fruits of the award with me and, more importantly, continue to have fun doing impactful research in the interests of forests and forestry globally.”
Meanwhile, Dr Eshchar Mizrachi, a senior lecturer at FABI, is one of four scientists in South Africa to be awarded a highly prestigious P rating for research on understanding the molecular biology of polysaccharide metabolism, especially cellulose and xylan, during wood formation in Eucalyptus trees. This rating is assigned to researchers normally under 35 years of age who have held a doctorate or equivalent qualification for less than five years at the time of application. His research primarily focuses on constructing a model of the regulatory network (genes, proteins and pathways) that play a role in influencing the partitioning of carbon and the deposition of cellulose and xylan in wood, and identifying candidate pathways or processes for biotechnological improvement of trees (applied via breeding using molecular selection tools, or genetic modification).
Prof. Slippers, Director of FABI, said, “These recent ratings show that we do not only compete locally in terms of excellence, but also with the best in the world. It is exciting to have both established world leaders and upcoming young and leading scientists in FABI. That is good for the future of the institute and University, and shows that we have a vibrant academic environment.”
All three scientists are academically linked to the Department of Biochemistry, Genetics and Microbiology. Head of Department Prof. Paulette Bloomer said, “It is a true privilege to be the academic home of these world-leading scientists, to share their passion for discovering the fundamental basis of biology, and to do research that is locally and internationally relevant.”
In addition to these A and P ratings, so far in the current round of awards and renewals of NRF ratings, UP academics have received a total of no less than 30 new ratings, and 49 renewed ratings, of which 2 are A ratings, 20 are in the B category, with 43 C and 9 Y ratings. The University of Pretoria now hosts 507 rated researchers, representing about 12% of the total number of rated researchers in South Africa.
Prof. Stephanie Burton, UP Vice-Principal for Research and Postgraduate Education, said the University is proud of the achievements of all these academic colleagues. “We are one of the biggest producers of university research in the country and Africa, and we produce research that is relevant and which matters.”
