Single-Cell RNA-Seq Analysis Identifying Cell Types in the reprogramming cells derived from hUCs on day 60.

a. Uniform manifold approximation and projection (UMAP) delineate 8 clusters and 3 cell types in the reprogrammed cells derived from hUCs on day 60.b. Distributions of different cell clusters populations.c. Hierarchical clustering of different clusters populations based on their global gene expression filed. Gene ontology analyses reveals the enriched terms of each cardiomyocytes clusters.e. UMAP analysis of UCell scores of overall cardiac gene expression of the 13-week embryonic stages matched with different cardiomyocyte clusters. UCell scores of left/right ventricular and atrial gene expressions of different embryonic stages matched with different cardiomyocyte clusters.
