To assess the expression levels of MPO and TRH in various cell types within AML, our data indicated that the gene expression levels of MPO and TRH, both in the overall LSC population and in the early haematopoietic stages of HSC‐like, prog‐like, and GMP‐like cells, were higher in CR patients than in non‐CR patients. The gene discussed is MPO; the disease is acute myeloid leukemia.
