Breakthrough in stem cell culturing
"Now, for the first time, we can produce large quantities of human embryonic stem cells in an environment that is completelychemically defined," says professor Karl Tryggvason, who led the study. "This opens up new opportunities for developing different types of cell which can then be tested for the treatment of disease."
Together with researchers at the Harvard Stem Cell Institute, the researchers have also shown that in the same way they can culture what are known as reprogrammed stem cells, which have been converted "back" from tissue cells to stem cells.
