A gene mutation that causes problems for neural stem cells – the building blocks of the brain – could be corrected by adding carnitine.
When it comes to stem cells, the ways that informed consent has been obtained in the past are not sufficient and improvements are needed.
Empty sample tubes wait to be filled in a blood and urine sample freezer. South Africa has no legislation governing biobanks that deal with human biological material.
South Africa has no legislation setting out the rules for biobanks and the guidelines that do exist are not clear or detailed. This leaves the door wide open for unethical practises.
Although safe bone marrow harvesting has taken place in South Africa for more than 50 years, there are many unproven stem cell treatments on offer.
Unless the South African government tightens its laws that govern stem cell treatments, unproven stem cell therapy will continue to surge.
Demonstrators dressed as embryos gather outside the French parliament to protest laws authorising research on embryonic stem cells. Across the world, countries are implementing additional laws to use treatments that are still in trial phases.
Many countries are introducing legislation and allowing practitioners to use medication still undergoing trials but that show preliminary signs of being safe, including some stem cell treatments.
Legislation in South Africa needs to be updated to accommodate the development in stem cell research and therapies.
South Africa may have legislation broadly guiding stem cell research and treatment, but these laws must be updated and clarified for it to be effective.
Embryonic stem cells.
Stem cell research and therapy have become buzzwords across the globe. Although some of the treatments are controversial and unsafe, there is also a great deal of excitement and promise.
Human bone marrow stem cells.
Stem cell research and therapy has taken the world by storm. Here's what you need to know about it.
Ok, when will it come back?
Plucking hairs from the scalp causes surrounding hairs to regenerate, and could be a novel treatment for alopecia sufferers.

Damage to vital organs, the spinal cord, or limbs can have an enormous impact on our ability to move, function – and even live. But imagine if you could restore these tissues back to their original condition…
We have a lot of cells, but where did they arise from?
In a paper published in Cell yesterday, scientists from the US and Thailand have, for the first time, successfully produced embryonic stem cells from human skin cells. That sounds interesting, but what…
The nucleus of a cell containing an individual’s DNA was transplanted into an egg cell that has had its genetic material removed.
Scientists have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any…
