Everyday, adipocytes in our bodies need to be replaced by new cells in a process called adipogenesis. Adipocytes develop from cells called preadipocytes that change their cellular identity to take on the role of the mature adipocyte. Different kinds of preadipocytes live in adipose tissue, and in this movie cells that are part of a cellular lineage that express the Trpv1 gene are green, while other cellular lineages are red. The cells that makeup the long, thing green vasculature structure have acted as preadipocytes, undergoing adipogenesis to form the green fat cells on the top and bottom of the movie.
