As shown in Table 1, many of the molecules are specific to cancer types, though a few other molecules like CD133, CD44, ABCG2, Aldehyde dehydrogenase (ALDH), and pluripotency markers like octamer binding transcriptional factor 4 (OCT4), SOX2, and NANOG are expressed by a wide variety of cancers, including hematological malignancies and solid tumors. This evidence concerns the gene PROM1 and hematologic disorder.
