Bone morphogenetic protein signaling in stem cells--one signal, many consequences.
Bone morphogenetic protein (BMP) signals play key roles throughout embryology, from the earliest patterning events, via tissue specification, through organ development and again in germ cell differentiation. While both input and the transducer molecules are rather well studied, the final outcome of a BMP signal is basically unpredictable and differs enormously between previously studied cell types. As already suggested by their name, BMPs exhibit most of their (known) functions on stem cells and precursor cells, usually driving them into various types of differentiation or death. In this minireview, some prime examples of BMP effects on several very different stem-cell types are discussed.
