Figure Lengend Snippet: Cellular composition switch of freshly isolated human dental pulp stem cells (hDPSCs) upon in vitro culture. a UMAP visualization of monolayer cultured cells (red dots) compared to the freshly isolated cells (blue dots). The purple dash circles highlighted the most overlapped zone in both conditions. b UMAP visualization of 14 color-coded clusters of integrated freshly isolated and 10-day in vitro cultured hDPSCs. Four major cell types are identified, including dental pulp cells, endothelia cells, immune cells, and glial cells. Cluster 4 cells present in both datasets. c Differentially expressed genes in cluster 4 from fresh and cultured datasets were listed in the blue and pink circles, respectively. The overlapped gray region highlights the genes with similar expression levels in cluster 4 from both datasets. Expression dynamics along the pseudotime of selected genes from left panel was plotted by Monocle3. d The distribution (left) and quantification (right) of selected stem cell surface makers genes (MCAM, JAG1, and PDGFRA) expression in both cultured and fresh hDPSCs. Cells with low and high expression were marked with gray and purple color, respectively
