Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

... the embryo itself. In research conducted on chick embryos since 1992, his team discovered that a group of very young embryonic cells called “precardiac endoderm?sends strong signals that cause adjacent cells in the embryo to become cardiac myocytes. Based on this finding, Dr. Lough reasoned that precardiac ...
