Please discuss fibroblast growth factor?

Can't w/ 400 charact: Great question, but almost impossible to discuss with 400 characters. Wikipedia does a nice job. Fgf has 22 subtypes. It is a chemical signal to help "fibroblasts" grow and function. It helps with wound healing and growing blood vessels. Nih research grants are spent to discover how it works and how we can use it to our advantage, or in some cases block it if a cancer cell needs it to spread.

Can't do justice: It is impossible to fully discuss the importance of fgf. Most organisms are composed of 3 basic structures: endoderm, mesoderm, and ectoderm. Fibroblasts are the most basic structure of the mesoderm and essentially responsible for forming the scaffold and structure upon which all layers are built. Fgf ( and there are more than 20 subtypes) regulate the growth and differentiation of all 3 layers.
