Extended Data Fig. 2: External references validate cell type annotations and multimodal clustering.

a) Tile plots showing mapping of each of the 28 cell clusters in the CITE-seq dataset (n = 9 donors, age 2.1-31.3, 3 male, 5 female) to the external dataset of Stuart et al.18. Colors depict the proportion of cells in each cluster assigned to each reference cell type. b) As in a), but for the external DISCO single-cell reference map19.
