Epidermal Growth Factor (EGF) is known for its role in promoting cell division and cellular differentiation in developing animals, but we know surprising little about what EGF does in vivo in mature adult animals.
Furthermore, the researchers found that they could categorize the growth factors based on their effects on differentiation. One group of growth factors appeared to inhibit endodermal and ectodermal cells, but allowed differentiation into mesodermal cells. A second group induced differentiation into ectodermal and mesodermal cells, and a third group allowed differentiation into all three embryonic lineages.
