The reported tumor stem cell markers also included Aldehyde dehydrogenase (ALDH1) [232], Musashi-1 [233], LgR5 [234], the prostate stem cell antigen (PSCA) [235], Doublecortin and CaM kinase-like-1 (DCAMKL-1) [236], and acute myeloid leukemia (AML) stem cell-surface marker TIM3 [237]. Here, PSCA is linked to acute myeloid leukemia.
