Fig. 4From: Self-organized insulin-producing β-cells differentiated from human omentum-derived stem cells and their in vivo therapeutic potentialAnalysis of cell surface receptors (SDC4 and TGF-βR3) and cell–cell junctions related to insulin secretion by β-cells (NCAM1, CX36, CX43, and E-cad). A Gene expression of cell surface receptors and cell–cell junctions related to insulin secretion by β-cells. B Immunofluorescence staining images of DAPI (blue), PDX-1 and E-cad (red), Cx36 and Cx43 (green), and insulin (yellow). Data represent the mean ± SD, *p < 0.05; ***p < 0.001. Scale bar = 200 μm.
