CD47 (don't eat me signal) expression levels and its relationship with clinicopathologic features in early-stage prostate carcinoma.

The CD47 molecule is basically a molecule that inhibits macrophage activation. CD68 is mostly used for macrophage classification, while CD163 is used for tumor-associated macrophage classification. Unlike others, we IHC examined CD47, CD68, and CD163 expressions in the surgical materials of patients who were operated for prostate carcinoma. In addition, we concluded that strong CD47 expression was closely associated with strong CD68 and CD163 expression in all tumor samples. However, a significant relationship between these expression levels and survival could not be demonstrated.
