Regrowth of Zebrafish's Tail Fin may Offer Clues for Treating Human Injuries

...s the fate of these as-yet undeveloped cells as an embryo forms. Through a cascade of signals, cells waiting for their calling learn which spot to take to help form the embryo, what kinds of cells to become there, and how many cells like themselves should be reproduced. These streams of signals also tell st...

... stimulate cell division in a lab until the cloned embryo is ready to be implanted into a female host animal. As this is the case the public may have the final say. The FDA has agreed that a final decision will only be taken after public opinion is garnered within a time period of three months. Debate s...

A Transplant in Time - Scientists ID Window for Tissue Transplant

...unity during which cells taken from the developing embryo can be most successfully transplanted. Tissues taken too early, when they are still fairly undifferentiated, may form tumors, while those taken too late can be identified as foreign, causing the host to reject them. By taking spleen tissue from emb...

Sugars in Liver Found to Clear Fats from the Bloodstream

...roughout all tissues would lead to the death of an embryo or death shortly after birth. “By selectively mutating a single tissue in mice, in this case the liver, we avoided a lethal effect,” said Esko.
