Researchers in China announced in a paper published in the journal Science on Thursday that they have developed an "easy and safe" way to make stem cells that could rekindle the great hope for growing tissue and organs from stem cells to treat a range of diseases. By using a cocktail of small molecules to chemically reprogram the adult tissue cells they say they can make induced pluripotent stem cells (iPSCs) as versatile as embryonic stem cells, without running the risk of dangerous mutations or cancer that occurs when gene insertion is used to make iPS cells...
