CD34 and acute myeloid leukemia: Prognostic subgroup analysis further showed that BMresLC calcium and stemness profiles partially recapitulate features of adverse-risk AML, including differences in CD34, CD38, PD-L1, MMRN1, LAPTM4B, NFATc2, and STIM2 expression.<h4>Conclusions</h4>Our findings identify a distinctive calcium- and stemness-based signature in BMresLC, representing a pre-MRD survival state characterized by slow cycling rather than enrichment in strict quiescence.
