Single cell RNA sequencing from stroma in the E16 salivary gland

Purpose: Use scRNA Seq to find B10stromal subpopulations and define how these subpopulations contribute to salivary gland proacinar differentiation. Method: scRNA Seq on stromal enriched cells from E16 salivary glands. Model closely related cells using PCA and UMAP regressions. Find genes that broadly and specifically define cell subpopulations. Results: The epithelium and stromal fibroblasts have multiple subpopulations. Stromal cells can be subdivided by their expression of Pdgfra, Pdgfrb, Thy1, Wnt2, and Acta2. Conclusions: Pdgfra expressing stroma specifically use BMP7 to promote proacinar differentiation. Overall design: Transcriptome analysis of stromal cell subpopulations
