Figure Lengend Snippet: a Reaggregation of iPSc-derived TEPs with primary human ETPs to form hTOs (human Thymic Organoids) cultured in a 3D fibrin hydrogel at an air-liquid interface in medium supplemented with RANKL, IL7, SCF, and FLT3L (Created in BioRender. Guillonneau, C. (2025) https://BioRender.com/apk8n61 ). b Bright-field images of hTOs (human Thymic Organoids) at 24 h and D4 showing a compact spheroid core with a peripheral cellular crown (identical magnification) ( n = 12 from independent differentiations and ETP donors). c scRNA-seq of EPCAM + CD45 − cells from D7 organoids with UMAP embedding and cell-cycle scoring (10x Genomics; Seurat workflow). d Module score for a TEP gene set: PDPN , PAX9 , IL7 , EBF1 , FN1 . e Integration of the EPCAM + CD45 − scRNA-seq dataset (Clusters 1, 2, and 3) with the Bautista human TEC atlas; with reference cells in gray. f Cell type deconvolution of TEPs and CD205 + TEPs against the EPCAM + CD45 − scRNA-seq dataset. g Distribution of the Tau tissue-specific variability index within clusters 3 and 1. Tau was computed from GTEx tissue expression data; TRA enrichment was assessed on the top-200 cluster-specific genes. Source data are provided as a file. h Assessment of the TRA repertoire in Cluster 3, showing enrichment for brain antigens. Source data are provided as a file.
