We classified 7,580 stromal cells into seven clusters, including endothelial cells expressing PECAM1 and CDH5, as well as six other MSC types including FAP+ cancer-associated fibroblast, MCAM+ perivascular-like cells (PVL), CXCL14+ cancer-associated fibroblast (CAF), CXCL12+ inflammatory CAF (iCAF), ICAM1+ telocyte, and ACTG2+ myofibroblast (Figure 3A and B). The gene discussed is ICAM1; the disease is cancer.
