## Abstract Throughout postnatal years, medullary adipocytes (MAs) increase in both number and size; however, knowledge of these cells pales in comparison to that of other adipocyte depots. It is widely hypothesized that MAs derive from multipotent progenitor cells of the bone marrow, such as human

β¦ Synopsis
The increase of adipose tissue mass that accompanies obesity is due both to an increase in adipocyte number (hyperplasia) and size (hypertrophy) (Shepherd et al., 1993) (Fig. 1). Hyperplasia results from the recruitment of preadipose cells from a population of pluripotent stem cells that reside in the vascular stroma of adipose tissue. These stem cells have the capacity to undergo commitment to adipose, muscle, bone, or cartilage lineages (Young et al., 1995). Both processes, i.e., commitment and hyperplasia to the adipose lineage, can be mimicked and studied separately by using established stem and preadipocyte cell lines in culture. When treated with
