From: Human dental pulp stem cells attenuate streptozotocin-induced parotid gland injury in rats
Effects of transplanted human dental pulp stem cells (hDPSCs) on different parotid cell subpopulations. Representative haematoxylin and eosin staining and number of vacuolations (A–D). Representative immunofluorescence staining for and number of aquaporin 5 (AQP5)- (E–H), cytokeratin 7 (CK7)- (I–L), and α-smooth muscle actin (α-SMA)- (M–P) positive cells in the control, diabetic (streptozotocin [STZ]), and transplanted (STZ + hDPSCs) groups. ***p < 0.001, compared with the control group; ###p < 0.001, compared with the STZ group. Data are expressed as means ± SEM. n = 10 for each group. Scale bars = 200 μm (A–C) and 500 μm (E–G, I–K, M–O)
