To determine if the presence of VSLSLCs and/or SLSLCs is not limited to HL-60 (Supplementary Figures S1 and S2), we analyzed the levels of CD34, CD45, and CD56 markers in two other myeloid leukemia cell cultures: KG1a—Acute Myeloid Leukemia (AML) and K562—Chronic Myeloid Leukemia (CML during blast crisis) (Figure 1 and Figure 2). The gene discussed is NCAM1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
