Geron has been rolling out tangible results for human embryonic stem cell work of late - a good thing given the current anti-research political atmosphere. The closer science is to cures, the harder it will be for politicians to be shut down or ban research. This latest Geron press release describes progress towards regenerative medicine for diabetes: "Insulin-producing cells can be differentiated from human embryonic stem cells (hESCs). ... Differentiation of pancreatic islet cells from embryonic stem cells is very challenging and protocols reported from work with mouse embryonic stem cells have not proven useful for human embryonic stem cells. We are focused on improving the yield and purity of hESC-derived islet cells to advance our preclinical studies in models of diabetes."
