A research team based in Australia and Italy described animal experiments in which 1 in 4 vitrified cow eggs were fertilized and later grew, by around day 5, to the blastocyst stage.Solving mysteries of reproduction helped make parenthood possible for millions|Robin Marantz Henig|June 9, 2021|Science News
Back in 2018, a team grew similar blastocysts from mouse stem cells—an admirable effort, but not a perfect model as mice and humans have different development trajectories.
Scientists know that during a pregnancy, a fertilized egg develops into a blastocyst around day four, and it then implants around day eight.
Though they didn’t get beyond the blastocyst stage, both models are by far the most complete replicas of an early human embryo to date.
For instance, last week, Zernicka-Goetz posted a preprint describing how her lab coaxed stem cells to self-assemble into a version of a human blastocyst, as a week-old embryo is known.Scientists plan to drop the 14-day embryo rule, a key limit on stem cell research|Antonio Regalado|March 16, 2021|MIT Technology Review
