FN expression and secretion in the ESCC cell lines (Eca-109, TE-1) and MSCs. Immunofluorescence (a) (× 200) and RT-PCR (b) showed that FN protein and mRNA was expressed at low levels in ESCC cells and high levels of FN protein and mRNA in MSCs. c ELISAs showed high concentrations of FN in MSC-condition medium, demonstrating secretion of high levels of FN by MSCs. Scale bar = 100 μm
