NettetBy identifying trajectories that connect cells based on similarilty in gene expression, one can gain insights into lineage relationships and developmental trajectories. Often called pseudotime, but doesn’t have to relate to cells in different times in a process (could be spatial differences). Nettet26. jul. 2016 · Gene expression along this differentiation path is distinct from other lineages such as endoderm, mesendoderm, and neural ectoderm. Single-cell analysis exposed the heterogeneity of differentiating cells and allowed discrimination of non-neural ectoderm and otic lineage cells from off-target populations. the z world

Nettet21. jan. 2024 · Monocle 3 would have assigned disconnected trajectories to the separate clusters, but those clusters have been labeled NPCs or neurons, which must have come from neural stem cells. However, some lineages do seem reasonable, such as curves 2, 3, 5, and 7, going from qNSCs to neurons, though some lineages seem duplicated. Nettet13. mai 2024 · Lineage trajectory analysis identified a progenitor origin that was reproduced in human trophoblast stem cell organoids. Heightened expression of basal cell adhesion molecule (BCAM) defined this primitive state, where BCAM enrichment or gene silencing resulted in enhanced or diminished organoid growth.
