Through screening and analysis of small molecular compound that potentiated differentiation of human induced pluripotent stem (hiPS) cells into pancreatic beta cells, we found that activation of Wnt signal increased beta cell differentiation in hiPS cells, and that our previously identified VMAT2-monoamine as a negative regulator for pancreatic differentiation, also applied to hiPS cells. We also identified domperidone (DPD), a dopamine D2 receptor (DRD2) antagonist, as a compound that enhances beta cell mass. In adult islet dissociation cultures, beta cell loss occurs through dedifferentiation, which was prevented by DPD. Dopamine modulates beta cell mass through DRD2 and exerts an inhibitory effect on adenosine signaling, a previously identified beta cell mass positive regulator. We believe that our knowledge on regulation of beta cell differentiation and cell mass regulation would be profitable for future manipulation of hiPS-derived beta cells.
