The percentage counts of CD203c+ cells among CD34+/CD45+ CML cells ranged between 3.4% and 21.7% and were thus higher than the percentage counts of CD203c+ stem- and progenitor cells in normal BM samples (range: 0.7%–1.5%) (Figure S2). Here, PTPRC is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
