The survival and differentiation of transplanted human dental pulp stem cells (hDPSCs) into acinar, ductal, and myoepithelial cells in the transplanted (streptozotocin [STZ] + hDPSCs) group. Number of PKH26-labelled hDPSCs co-expressing aquaporin 5 (AQP5) (A–D), cytokeratin 7 (CK7) (E–H), and α-smooth muscle actin (α-SMA) (I–L). Some PKH26 + AQP5 and PKH26 + CK7 cells exhibited acinar and duct-like arrangements, denoted with a white line (C, D, G, H), suggesting cellular organisation into functional components. PKH26-labelled cells (red) C, G, K; AQP5-positive cells (green) B, CK7-positive cells (green) F, α-SMA-positive cells (green) J; DAPI-stained nuclei (blue) A, E, I. Merged images (D, H, L). Scale bar = 50 μm (A–D and I–L) and 75 μm (E–H)
