Additionally, tumor stem cell and TA populations of Min and MSH2KO epithelial tumors had a larger number of cells co-expressing cell proliferation makers (Hgmn2, Mcm5, Top2a, Mki67) compared to BLM epithelial tumors (Figure 5B) consistent with the proliferative nature of ProCSCs [48]. This evidence concerns the gene MKI67 and neoplasm.
