Synthetic embryos complete gastrulation to neurulation and organogenesis

- f6v 4y agoIt’s often money. I’d run dozens of experiments, but some reason Forbes top 100 don’t want in the queue in front of the lab. But also, there might be lack of results beyond that time point.

- XorNot 4y agoThis work was done in mice. These are mouse embryos.
- ljlolel 4y agoNot saying they’re the same but humans essentially look like fish, chickens, pigs (gils, tails, etc) for the first few weeks.
- 01acheru 4y agoIt is up to one's empathy, but mercy isn't something strictly directed towards humans. For some people it is universal, others have no mercy even for fellow humans.

- mschuster91 4y agoEthics. I mean, yes it's "only" mice, but still - there is no point in letting them develop into animals that can actually feel harm for no purpose, at least not until the feti are similar in development quality to naturally grown feti.
- Tade0 4y agoObligatory IN MICE The length of a mouse pregnancy is ~20 days. I wonder how does such an embryo compare to a natural one?
- credit_guy 4y agoWow. So 8.5 days is almost the half-point of the pregnancy.
- derbOac 4y agoI think a more accurate title for these sorts of things is "Synthetic embryos look like they complete gastrulation to neurulation and organogenesis". Still impressive but with these sorts of things it's the unknown unknowns that are the problem.
