ACTA2 and cancer: Using scRNA-seq data, we investigated the expression of genes involved in stromal-like signature (FAP, VIM, and ITGB1); cancer-associated fibroblasts (CAFs; POSTN and ACTA2); as well as COL1A1, SULF1, TCF21, and DLK1, which were previously associated with FAP-high or FAP-low CAF phenotypes in OC.23
