Fig. 2

CAFs promote PSN1 cells proliferation, invasion and migration. A CCK8 assay was performed in PSN1 cells. B Colony formation assay was performed in PSN1 cells. C The transwell assay was used to assess PSN1 cells’ capacity for invasion. D Assays for wound healing were used to evaluate PSN1 cells’ capacity for migration. The data is shown as mean ± SD. Analyses were performed by one-way ANOVA, and the Sidak test was used as post hoc. *p < 0.05; **p < 0.01; ***p < 0.001
