doi: 10.1038/s41586-025-09018-7
Figure Lengend Snippet: a , Circos plot showing leukaemia cell surface receptors and cognate stromal-cell-derived ligands. b , Kaplan–Meier curves of human patients with leukaemia with low (<11.14, n = 80) or high (≥11.14, n = 81) SLC6A6 expression (TCGA-LAML; Xena Browser; log-rank test). CI, confidence interval; HR, hazard ratio. c , Normalized SLC6A6 expression in CD43 + cells from normal human bone marrow (BM) samples and samples from patients with bcCML and AML. n = 7 (bone marrow), n = 10 (bcCML) and n = 11 (AML). For the box plots, the centre line shows the median, the box limits show the interquartile range and the whiskers represent the minimum and maximum values, respectively. Statistical analysis was performed using DESeq2-implemented Wald tests. d – g , Representative IHC images ( d , f ) and quantification ( e , g ) of CDO1 expression in matched patient bone marrow biopsies at MDS diagnosis and after AML transformation ( d , e ), or at AML diagnosis (AML-D) and relapse (AML-R) ( f , g ). n = 5 independent patients per cohort. Each colour represents a patient sample. Statistical analysis was performed using two-tailed ratio paired t -tests. h , The strategy used to determine the impact of inhibiting CDO1 in human bone marrow MSCs on co-cultured AML cells (MSCs and AML cells were derived from the same patient). CFU, colony-forming unit. i , The number of live LSCs (left; data are mean ± s.e.m.; n = 11 independent culture wells per cohort; data were combined from two independent experiments) and their colony-forming ability (right; data are mean ± s.d.; n = 3 independent culture wells per cohort) after coculture with AML MSCs. j , Taurine quantity per femur in control and leukaemic mice, as determined using colourimetric analysis, 12 days after transplant. Data are mean ± s.e.m. n = 5 animals per cohort. Data were combined from two independent experiments. For i and j , statistical analysis was performed using unpaired two-tailed Student’s t -tests. k , Experimental strategy and survival curve, showing the impact of blocking taurine production by MSC/osteolineage populations in vivo on bcCML progression in unirradiated recipients. n = 18 ( Cdo1 fl/fl / Cdo1 +/+ ) and n = 14 ( Cdo1 fl/fl Prrx1-cre + ). Data were combined from four independent experiments. Statistical analysis was performed using the log-rank test. WT, wild type. Scale bars, 50 µm ( d and f ). The mouse images in h and k are adapted from ref. , Springer Nature America.
