UMAP projection of cell differentiation trajectories predicted for each sample. RNA velocity trajectories were analyzed separately for each sample to avoid batch differences. The data were plotted as streamlines on the UMAPs computed by CellRank for each sample, to avoid potential artifacts introduced by co-embedding all samples together. The cells were colored by their cluster assignments in the integrated data (Fig. 1). Thus, some cells of the same color may become separated in these UMAPs, compared to the one in Fig. 1. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
