Results showed that the cells with mesenchymal-like morphology deriving from the ovarian cancer tissues of patients with OSA had higher CD31, CD117, CD106, AC133, and CD146 expression and moderately increased CD34 and Flt-4 expression, but lower CD24, CD49d, CD49f, EGFR, and SH2 expression, compared to cells deriving from normal ovarian tissue (Figure 5). Here, PROM1 is linked to ovarian cancer.
