WebCell-specific RNA velocity estimates provide a natural basis for quantitative modeling of cell fates. Metabolic labelling showed that for most genes, changes in the spliced/unspliced ratio would be detectable after 10 - 100 minutes (Extended Data Fig. 2). WebBy exploiting the abundance of unspliced and spliced mRNA, one can infer the RNA velocity of individual cells, i.e., the time derivative of the gene expression state of cells. Whereas traditional trajectory inference methods reconstruct cellular dynamics given a population of cells of varying maturity, RNA velocity relies on a dynamical model ...
