Fig. 2From: Atf4 regulates angiogenic differences between alveolar bone and long bone macrophages by regulating M1 polarization, based on single-cell RNA sequencing, RNA-seq and ATAC-seq analysisCharacterization of ABM single-cell atlas. A Cells identified by scRNA-seq were visualized with Tsne (left) and UMAP (right). Different cell populations were defined and distinguished by color. Each point represented an independent cell. B The expression levels of cell markers were projected onto UMAP atlas. C Specific expression of cell markers in different cell types. D Cells identified from mesenchymal cells were visualized with UMAP; E Specific expression of cell markers in the four stromal cell subtypes.
