Figure 10. Adipocytes are derived from both resident mesenchymal cells in the stromal-vascular fraction of adipose tissue and hematopoietic progenitors that reside in the bone marrow. In addition to adipocytes, mesenchymal progenitors can form other connective tissue cells, such as myocytes and osteocytes. Myeloid progenitors derived from hematopoietic progenitors in bone marrow give rise to adipocytes as well as neutrophils, macrophages, dendritic cells, and granulocytes.
