Additionally, immunofluorescence staining of tumor sections for tdTomato+ vascular endothelial cells (CD31+) and smooth muscle cell/pericytes (PDGFR-β+, Desmin+, or α-SMA+) demonstrated markedly greater pericyte coverage of endothelial cells in the TNFSF15-treated group than the vehicle-treated group (Figure 3G–I). Here, ACTA1 is linked to neoplasm.
