Summary:
The Toronto Star reports researchers at McMaster University have revealed how embryonic stem cells turn into different types of human tissues:
"A landmark discovery by researchers at McMaster University could radically alter the way scientists can use embryonic stem cells to grow replacement tissues and treat cancer. In a surprise revelation, a McMaster study found that human embryonic stem cells – “the great grandmothers” of all the other cells in our bodies – build themselves a nurturing cocoon that feeds them and directs their ability to transform into other types of tissues."
The researchers also discovered a way to manipulate embryonic stem cells to become organs and tissues, and stop tumor growth in cancers:
"And by manipulating the products of this tiny, cellular placenta, it may be possible for scientists to prompt the stem cells to grow into desired tissues and organs, or to switch off tumour growth in cancers, says Mickie Bhatia, the lead study author. The study will appear in an upcoming issue of the leading scientific journal Nature."
