population of brown fat. Progenitors of traditional white fat cells and adrenergically induced brown fat do not have the capacity to activate the Myf5 promoter. Both adipocytes and brown adipocyte may be derived from pericytes, the cells which surround the blood vessels that run through white fat tissue. Notably, this is not the same as the presence of Myf5 protein, which is involved in the development of many tissues.

Additionally, muscle cells that were cultured with the transcription factor PRDM16
