Morphology characteristics and identification of fibroblasts. Magnification, ×200; scale bar = 50 µm. (a) Morphology characteristics of nasal mucosal fibroblasts of guinea pigs: (A) primary fibroblasts cultured for three days, (B) primary fibroblasts cultured for eight days, (C) F3 generation fibroblasts cultured for three days, and (D) F3 generation fibroblasts cultured for five days. (b) Identification of fibroblasts by immunocytochemical staining of vimentin: (A) vimentin is positively expressed in fibroblast cytoplasm; (B) no expression of vimentin was observed in the negative control group. The nuclei were counterstained with hematoxylin (blue).
