Extended Data Fig. 6: Inferred developmental trajectories of trophoblast cell populations.
From: Cell type and cell signalling innovations underlying mammalian pregnancy
a-f. Force atlas embeddings of trophoblast cell types overlaid with RNA velocity (scVelo45) vector fields showing developmental directionality. g-l. PAGA connectivity graphs, where edge weight corresponds with transition probability. Thresholds for plotting edges were selected based on the density of the graphs: low (0.02; opossum and macaque) medium (0.10, guinea pig and tenrec) or high (0.20, human and mouse). Human data (f,l) lack velocity information but a spatially-verified developmental trajectory is available in the original publication5.
