ACTA1 and neoplasm: To confirm that CAF present in primary tumor tissues overexpress hMENA/hMENAΔv6, we performed confocal analysis of NSCLC and PDAC tissues co‐stained with Pan‐hMENA and α‐SMA antibodies, showing that Pan‐hMENA decorates α‐SMA‐positive stromal cells and, as expected, also tumor cells which were α‐SMA negative (Fig 2A and B).
