CD47 and cervical squamous intraepithelial neoplasia: Although WT tumors are generally unaffected by anti-CD47 and anti-Tyrp1 (Dooling et al., 2022; Hayes et al., 2022), we hypothesized that we could eliminate CIN-afflicted WT B16F10 tumors by providing adoptive transfer of marrow to increase macrophage numbers to compensate for the CD47-mediated inhibition of endogenous macrophages.
