WebbJiang et al. provide a single-cell transcriptomic census of the cynomolgus macaque placenta during gestation and bioinformatic evidence for stage-related features of cells at the maternal-fetal interface, the potential origin of placenta villous core cells, and the cross-species maternal-fetal features of macaques. They also present a comparison with data … WebbPseudotime analysis is, perhaps, one of the major analysis that can be carried out in SC data. It aims to depict a trajectory, a sort of order in which cells transition from A to B. What defines this process, and the starting and end point is heavily driven by the research question, the nature of the data and prior knowledge.

Our results suggest that differentiation reveals latent features of aging and that fate commitment decisions are delayed in aged myogenic cells in vitro. dave gaylord arbor financial group
