Remarkably, we found a positive correlation between INHBA expression in tumor cells and the surrounding expression of Activin A-exposure genes (FN1 or POSTN) in CAFs (Fig. 7b and Supplementary Fig. 15b), with preferential expression in tumor areas with High infiltrative morphology (Fig. 7c and Supplementary Fig. 15c). This evidence concerns the gene FN1 and neoplasm.
