Embryonic Stem Cells Hold More Promise

(From STLtoday.com). Scientists back embryonic stem cell research because it appears to give a greater chance of developing regenerative therapies for common age-related conditions. "Stem cells taken from a
patient's own muscle or blood failed to make functioning heart cells. Those adult stem cells homed in on damaged heart tissue and latched on, but never got the rhythm the rest of the heart ticked to ... Some of the patients in the study did improve after the therapy .. the [adult] cells may have recruited new blood vessels to the injured area and helped speed the healing." By way of comparison, "the embryonic cells did not just latch onto the wounded heart ... they actually became heart muscle cells that beat in time with the rest of the organ."
