We discovered that the spatial distributions of Fb_LRRC15, which represents the myCAF population, were highly correlated with pancreatic cancer cell distributions (Fig. 7D), whereas Fb_SFRP1 cells, representing iCAF, were located distal to the cancer spots (Fig. 7E), as can be expected from previous studies [57, 58]. This evidence concerns the gene LRRC15 and familial pancreatic carcinoma.
