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.
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.
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
