Microscopic images of the immunofluorescence detection of fibronectin in long-term FA-treated and untreated control Caki-1 and HK-2 cells. Representative immunofluorescence microscopic photographs showing the expression of fibronectin in untreated control and long-term FA-treated cells of Caki-1 (upper two panels) and HK-2 (lower two panels). Fibronectin staining is in red, whereas the nuclear staining by DAPI is in blue. The immunofluorescence staining of fibronectin was performed as described in the Materials and Methods. Scale bar = 100 μm.
