Why can’t we just use iPS cells instead of embryonic stem cells, and avoid the controversy?

Discovered in 2006, induced pluripotent stem cells (iPSCs) are still a new research field, and their potential to be used in the same way as embryonic stem cells is yet to be determined. Embryonic stem cells remain the “gold standard.” Reprogramming cells (the process of making iPSCs) may cause some differences that are not present in cells that are already embryonic in nature.  It is critical to explore all avenues of stem cell research, to see what will be the most useful for regenerative medicine. Learn more about the different types of stem cells.
