Figure 1. Identification of the gastric cancer associated fibroblasts (gastric CAFs), gastric para-mucosa fibroblasts (GPFs) and neonatal human foreskin fibroblasts (BJ) isolated from the GC tissue and para-carcinoma tissue respectively.

(A) The expressions of α-SMA, SDF-1, Vimentin and FAP in gastric CAFs, GPFs and BJ were detected by immunofluorescence; (B) The expressions of FAP and integrin αvβ5 in gastric CAFs and GPFs were detected by flow cytometry detection.
