Wnt signalling

Wnt Signaling Controls The Fate Of Stem Cells In Adult Brains: "Wnt proteins form a family of highly conserved signaling molecules that play a crucial role in controlling cell expansion and lineage decisions in many types of stem cells."

Forgotten by evolution?: "the scientists, using certain substances, were able to bring the stem cell line to express proteins characteristic of muscle cells. Interestingly, when a particular path, known as the wnt-signal path, was stimulated, the cells began to develop the features of heart muscle cells. In contrast, when they were beforehand stimulated with a protein known as CDO, the cells showed certain characteristics of skeleton muscle cells."
