CD44 and neoplasm: CD24 + cells have a high metastatic capacity and higher tumorigenic potential in vitro studies.[26,27] The overexpression of CD24 is related to low OS.[28] However, Ricardo et al found no relationship between CD24 expression and pathological parameters.[15] In vitro studies showed that CD44+/CD24 + tumor cells and CD44+/CD24‐ tumor cells differed in their stemness properties.
