Increased collagen I deposition at the periablational zone after incomplete RFA of HCC in an orthotopic animal model. a The increased collagen stained by Sirius Red was located at the periablational zone (black arrow) and surrounded the residual HCC foci. b Collagen I deposit (red-yellow color area) was observed using polarized light microphotographs of Sirius red staining-stained slides. c The increased collagen I at the periablational zone and around the residual HCC foci was verified by immunohistochemical staining. Scale bar, 50 μm
