Researchers at the Stanford University School of Medicine found that cells derived from human embryonic stem cells could repair damage in a mouse model of heart attack. The researchers first looked at which genes were active at every stage between the human embryonic stem cells and early heart muscle cells. The cells they implanted mirrored the genes that are active in the hearts of 20 week old fetal mice.

Researchers at the Stanford University School of Medicine have found that human embryonic stem cells trigger an immune response much like organ rejection when transplanted into mice. In the past, researchers had thought that transplanted embryonic stem cells might not be rejected the way transplanted organs are. Testing this theory, the team found that after transplanting human embryonic stem cells into normal mice, those cells disappeared within seven to ten days. In mice without an immune system the cells survived and even multiplied.
