Knockdown of Cldn2 in PTECs enhances fibroblast activation and proliferation. ( A ) Representative immunostaining images showing the nuclear localization of proliferating cell nuclear antigen (PCNA) in activated fibroblasts. Cells were immune-stained for α-SMA (red) and PCNA (green) and counterstained with DAPI (blue). White arrows indicate positive staining. Magnification ×400, scale bar =100µm. ( B ) Quantitative analysis of PCNA + /α-SMA + cells showed knockdown of Cldn2 in PTECs markedly ameliorated the activation and proliferation in fibroblasts by co-culturing with PTECs in NG for 48 hours. (C and D) Representative images and quantitative analysis show knockdown of Cldn2 in PTECs promotes fibroblast proliferation, as demonstrated by EdU incorporation.
