Researchers get primate embryos to start organ development in culture dishes

June 2, 2023

(Ars Technica) — Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post-fertilization, achieving key developmental landmarks never before observed in culture, including the start of organ development. The ability to track these processes in the lab might be an important step toward understanding congenital birth defects and organ development in humans.
