ScRNA-seq analysis of in vitro cultured monkey embryos


ABSTRACT: Primates embryo implants into the maternal uterus, forms three germ layers and begin early organogenesis, such as neurulation, heart formation, during the first 4 weeks of development. Although, this stage represents a milestone in early embryonic development of primate, our understanding remains limited. Here, we optimized our previously established in vitro culture system, which enable the ex-utero culture of cynomolgus monkey up to 25 days. Morphology histological, and single-cell RNA sequencing analyses confirm that the in vitro cultured embryos recapitulate key events of in vivo development. Using this platform, we delineate monkey early-stage lineage trajectory and genetic programs accompanying the neural, mesoderm and endoderm specification, as well as primordial germ cell–like cell (PGCLC). Thus, this culture system represents a valuable and easily accessible platform to study and manipulate early primate embryogenesis, which cannot easily accomplish in vivo.
