Cells at different passages (up to 8th) were analyzed by immunofluorescence detection using specific primary antibodies against smooth muscle (α-SMA, desmin) and myofibroblast (vimentin) markers, as well as the epithelial marker cytokeratin. AD: Representative images show a full immunopositivity for α-SMA (A), desmin (B), and vimentin (D). Immunostaining for cytokeratin (C) was absent. Original magnification ×10; scale bar = 100 µm.
