Figure 1. scRNA-seq reveals the different cell types and distribution among patients with or without MSCs treatment. (A) Cell annotation using the azimuth package (https://app.azimuth.hubmapconsortium.org/app/human-pbmc). And the referenced UMAP was leveraged to better visualized the results. (B) Cell distribution for all four groups. (C) Cell proportion of all cell types in four groups. (D) Bar plot shows the cell proportion of all cell types in four groups. (E) Cell distribution analysis indicates the largest cell proportion of CD14+ monocytes.
