TOKYO (AP) — Japanese researchers have discovered stem cells in human heart tissue, a development that could lead to improved treatments for heart disease and reduce the need for transplants, a Japanese newspaper reported Friday.Hmmmm. Might this also be relevant to to the ongoing debate on the moral implications of the use of embryonic stem cells?
This is one of those "continuums of acceptability" issues for me. The use of tissues from embryos started for the sole purpose of harvesting stem cells is way beyond my comfort level. Umbilical cord stem cells are acceptible to me. If the heart stem cells are truly totipotent, then this could be a major step forward in treating diseases and injuries.
