摘要:
Signaling by the canonical Wnt pathway has multiple functions in stem cells. It can either control stem cell expansion or--as we have recently demonstrated with neural crest stem cells-influence cell lineage decisions by promoting specific fates at the expense of others. Thus, the role of canonical Wnt in stem cells is dependent on cell--intrinsic properties that determine how a cell responds to Wnt. The molecular basis for the functional diversity of Wnt in different stem cell types remains to be elucidated.
