Following these initial reports, CD47 ligation-mediated cell death was confirmed in tumor cells of lymphoid (Mateo et al. 2002; Leclair et al. 2018), myeloid (Mateo et al. 2002), granulocytes (Mateo et al. 2002), dendritic cells (Johansson et al. 2004), ovaries (Mateo et al. 2002), and breasts (Manna and Frazier 2004). Here, CD47 is linked to neoplasm.
