ABSTRACT
Objective To conduct the in vitro study on the changes of gene and biological characteristics of different esophageal interstitial fibroblasts after their indirect contact wish esophageal cancer cell lines.Methods The mRNA levels of Vimentin,α-SMA,TGF-β1,HGF,MMP2 and MMP9 in normal esophageal interstitial fibroblasts(NFs),atypical hyperplasia interstitial fibroblasts(AFs) and cancer related fibroblasts(CAFs) and PCNA mRNA in esophageal carcinoma cell line were detected after their indirectly mutual contact.The invasion test of carcinoma cell line was conducted.Results From NFs,AFs to CAFs,the expression of Vimentin mRNA had no difference.The mRNA expressions of α-SMA,TGF-β1,HGF,MMP2 and MMP9 were gradually increased.After indirectly mutual contact with esophageal carcinoma cell line,the mRNA expressions of α-SMA,TGF-β1,HGF,MMP2 and MMP9 in NFs and AFs were up-regulated,and the difference was statistically significant(P<0.05),while the related mRNA expression in CAFs had no obvious change.The expression of PCNA mRNA in esophageal carcinoma cell line had no change after contact with NFs,but the expression of PCNA mRNA was significantly up-regulated after interaction with AFs contacting with CAFs.Conclusion The esophageal carcinoma cells and esophageal interstitial fibroblasts could affect the proliferation activity and invasive characteristics of counterparts.
