Stable stem cell commitment to the adipocyte lineage by inhibition of DNA methylation: role of the BMP-4 gene.

ABSTRACT: Previous studies showed that exposure of C3H10T1/2 stem cells to bone morphogenetic protein-4 (BMP-4) produced cells that convert into adipocytes at high frequency when treated with differentiation inducers. In the present investigation, an independent approach shows that BMP-4 is required for stable commitment of pluripotent stem cells to the adipocyte lineage. Exposure of proliferating 10T1/2 stem cells to 5-azacytidine, a potent DNA methylation inhibitor, gave rise to a subpopulation of cells that can be cloned and that have the capacity to undergo conversion into adipocytes upon treatment with terminal differentiation inducers. Detailed studies performed with a cloned committed subline, the A33 line, verified stable adipocyte lineage determination in the absence of exogenous BMP-4. Rem
