Recent advances in regenerative medicine have created a broad spectrum of stem cell research. Among them, tissue stem cell regulations are important issues to clarify the molecular mechanism of differentiation. Adipose tissues have been shown to contain abundant preadipocytes, which are multipotent to differentiate into cells including adipocytes, chondrocytes, and osteoblasts. In this study, we have first shown that megakaryocytes and platelets can be generated from adipocyte precursor cells. Human adipocyte precursor cells were cultured in conditioned media for 12 days to differentiate adipocytes, followed by 12 days of culture in media containing thrombopoietin. The ultrastructures of adipocyte precursor cell- and bone marrow CD34-positive cell-derived megakaryocytes and platelets were similar. In addition, adipocyte precursor cell-derived platelets exhibited surface expression of P-selectin and bound fibrinogen upon stimulation with platelet agonists, suggesting that these platelets were functional. This is the first demonstration that human subcutaneous adipocyte precursor cells can generate megakaryocyte and functional platelets in an in vitro culture system.
