Extended Data Fig. 4. SATURN annotates B cells in mouse and lemur spleen on a fine-grained level.
(a) UMAP visualization of SATURN’s embeddings obtained by integrating spleen cells from the human, mouse and lemur. B cells are shown in different colors based on ground-truth annotations while other cells are in grey. (b) UMAP visualization of expression of B cell marker Cd19. (c) Dotplot of Cd19 expression vs species and cell type. Cd19 is expressed in human memory B cells, mouse and lemur B cells, and only weakly in human naive B cells. This indicates that mouse and lemur B cells are correctly clustered with memory B cells.
