Among the stem-like populations, one seems to be previously undetected in ovarian tumors (the uppermost CSC cluster in Figure 2), where the cells express the stem cell markers CD133, CD34, CD47 and the lymphocyte markers CD4 and CD8 but not CD3, in addition to the tumor markers CD24 and EpCAM. The gene discussed is PROM1; the disease is ovarian neoplasm.
