Progress Continues in Non-Embryonic Stem Cell Science

Scientists from La Jolla, California have reported successful reprogramming of skin cells into cells with embryo-like potential. This was accomplished by introducing four key proteins into cells rather than inserting new genes as had previously been reported. This new technique is thought to be a safer alternative in that it avoids direct genetic manipulation of the cell that could result in unwanted changes in cell behavior. Progress in this area is particularly exciting in that it may offer an easier, safer and ethically acceptable alternative to human embryo derived stem cell research. While this technique (or any other alternative) will not silence the any-science at any-cost elitist crowd it does offer a great hope to responsible scientists primarily interested in improving human health without degrading the human condition.
