Vitamin C could play an essential role in the manufacture of stem cells for treating human diseases, new research suggests. The vitamin boosts the reprogramming of adult cells to give them the properties of embryonic stem cells.
Scientists who made the discovery believe it may help them overcome long-standing hurdles in the way of creating the reprogrammed cells, called induced pluripotent stem cells (iPSCs). IPSCs offer a solution to the ethical problems involved in producing embryonic stem cells with the potential to become any kind of human tissue, from bone to brain.
The U.S. government has given an ultimatum to the international group that helps provide vaccines to...
