Optimal transport of four lineages. To the left, a tetrahedral plot reports transport of ectoderm (blue), endoderm (yellow), NSM (orange), and PMCs (red) toward their respective vertices with the vertices reached by cells expressing cohort of genes for that lineage at 20hpf. To the right the same trajectories are reported on the UMAP. Gray cells are cells that have yet to reach 50% probability toward any of the fates.
