An interesting development in stem-cell research was just reported by Stem Cell & Regenerative Medicine International. Scientists have had a couple methods in the past to convert a patient’s own cells to stem cells but the methods had unacceptable risks for mutations. The new method uses skin cells and a cell-penetrating peptide (protein.) This avoids the risks of using retroviruses or chemical washes. Currently it takes longer but they believe the process can be refined.
Avoiding the thorny ethical issues of embryonic stem cells means research can progress rapidly. Also, using one’s own cells reduces rejection issues. Great progress…

Good news.
