Independent of the type of MPN or the driver gene (JAK2V617F or CALR), CD34+/CD38− NSC displayed the TGFB‐R‐related antigen endoglin (CD105), the SCF receptor KIT (CD117), and the IL‐3 receptor alpha chain (CD123) (Figure 2; Table S5). This evidence concerns the gene CD38 and myeloproliferative neoplasm.
