TAMPERING with stem cells from human embryos might be a political hot potato,
but the benefits could be huge. Already, scientists have coaxed human stem cells
to turn into brain, liver, muscle and beating heart cells. And results from
animal experiments hint that the cultured cells should function as normal when
transplanted. This could lead to new treatments for a host of diseases, such as
Parkinson’s.
Earlier this year, a team led by Alan Trounson and Michael Pera at Monash
University in Melbourne announced they had grown primitive muscle and nerve
cells from human embryonic stem cells
