Doxycycline-induced Pax4 stimulates β-cell proliferation in human islets. (A) Proliferation was measured by BrdU incorporation in dispersed islets expressing either Pax4 wt or R129W. Islets were cultured with or without 0.5 μg/ml of doxycycline in the presence of 10 μM BrdU. Immunocytochemical detection of BrdU incorporation (green) and nuclei staining (DAPI in blue) was performed 48 h later. (B) Forced expression of Pax4-induced proliferation in human islet β-cell replication as assessed by costaining of BrdU and insulin (arrows). Bars, 50 μM.
