1715-Modelling Mouse Embryogenesis from Stem Cells

Paper Talk · Oct 28, 2026 · 22m

Researchers successfully generated mouse embryo models starting exclusively from chemically induced totipotent-like stem cells, completely bypassing natural fertilization. These laboratory-grown structures self-organized into accurate blastocyst-like formations before progressing through crucial milestones like gastrulation, axis establishment, and early organogenesis. Over extended periods in culture, the models developed functional cardiac tissues and sophisticated extraembryonic compartments that closely mirror natural embryos. This innovative system provides an exceptional platform for…
