Cheap Stem Cell Treatment, Anyone? Stem cell treatments, even those that are unproven, are prohibitive when it comes to cost. But there is hope that stem cells will become more affordable in the future. Why should we be hopeful? Because researchers in Japan and the United States led by Dr Haruko Obokata have discovered an easier way to produce stem cells through a reprogramming phenomenon called stimulus-triggered acquisition of pluripotency or STAP. If this research holds up, it is likely to lead in cheap stem cell treatment procedures in the future.
