Figure 1:UMAP visualization of cell types at the early maternal-fetal interface. (a) Placental and decidual cell cluster analysis visualized by UMAP. Colors indicate cell type. (b) Origin of droplet cells in a by tissue (blood, decidua, and placenta). (c-h) UMAP visualization and violin plots of expression for perivascular cell-type-specific marker genes (MGP) (c and d), ACE2 (e and f), and AXL (g and h) in distinct cell clusters of the early maternal-fetal interface. UMAP: Uniform Manifold Approximation and Projection; DC: Dendritic cells; dM: Decidual macrophages; dS: Decidual stromal cells; Endo: Endothelial cells; Epi: Epithelial glandular cells; F: Fibroblasts; HB: Hofbauer cells; PV: Perivascular cells; SCT: Syncytiotrophoblast; VCT: Villous cytotrophoblast; EVT: Extravillous trophoblast; NK: Natural killer cells.
