New autism research: a nutrient called carnitine might counteract gene mutations linked with ASD risks

A gene mutation that causes problems for neural stem cells – the building blocks of the brain – could be corrected by adding carnitine.

How to make sure South Africa’s biobanks balance scientific progress with the law

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.

Why the world needs to keep pace with breakthroughs in stem cell research

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.

Why South Africa needs better laws for stem cell research and therapy

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.

Dream of regenerating human body parts gets a little closer

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? j.reed

Explainer: what are stem cells?

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…

Human embryonic stem cells grown from skin tissue

Scientists have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any…

Nobel prize winners prove that success can be cloned

The 2012 Nobel Prize for Medicine and Physiology has been awarded to John Gurdon and Shinya Yamanaka, “for the discovery that mature cells can be reprogrammed to become pluripotent”. A pluripotent cell…
