(E) Longterm culture initiating cell (LTC-IC) frequencies of the indicated groups at 4 weeks of in vitro culture (n = 6). (F) Typical surface marker abundance of the indicated transformed cell populations at 8 to 10 weeks in culture. (G) Venn diagram showing the overlap of significantly differentially expressed (DE) genes between HSC/CMP-MLLx and LMPP/ GMP-MLLx cells using DESeq2, ANOVA (on rlog transformed read counts) and ANOVA (on vst transformed read counts) as indicated. (H) Heatmap showing the 130 genes with consistently higher expression in LMPP/GMP-MLLx and the 45 genes with consistently higher expression in HSC/CMP-MLLx and their functional annotations according to webgestalt and Toppgene. (I) Selected stem cell–related gene sets from GSEA are shown comparing HSC-/CMP-MLLx (HC-MLLx) and LMPP-/GMP-MLLx (LG/MLLx) cells. In (A), (C), and (E), data are represented as means ± SD. In (C) and (E), statistical significance was determined by Student t test. Credit: Zeisig et al., Sci. Transl. Med. 13, eabc4822 (2021) 24 February 2021
