CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: We extracted total RNA containing the small RNA fraction (<200 nt) from sorted cells; given that individual patient-derived fractions had low yields of RNA, samples from different patients or HD were pooled before preparation of libraries for small RNA-NGS (CML-CP LSC-enriched CD34+CD38−CD26+, CML-CP HSC CD34+CD38−CD26−, HD HSC CD34+CD38−/dim, HD progenitors CD34+CD38+).
