What is an iPS (induced pluripotent stem) cell?
iPS cells are adult cells reprogrammed to behave like embryonic stem cells. While iPS cells are an exciting discovery, these cells could never be used in patients because the use of viruses to reprogram these adult cells predisposes the cells to cancer. As a result, these cells cannot replace the use of embryonic stem cells. There is widespread agreement among leading stem cell researchers, including the scientists that developed iPS cells, that research must continue on all types of stem cells including those derived from embryos. Some of the work announced in November 2007 was done at the University of Wisconsin by James Thomson. Early stages of this work used embryonic stem cells derived from leftover in vitro fertilization (IVF) embryos. This work would have been illegal in Michigan, illustrating how restrictions under Michigan state law stifle discovery and impair Michigan scientists’ ability to participate in critical research.
