Fetal Lamb in a Bag: Scientists Hope to Replicate for Humans

AI Thread Summary
Scientists have successfully used plastic bags to replicate amniotic sacs and plumbing to replace placentas in fetal lambs, with aspirations to apply this technology to premature human infants. There is uncertainty regarding the role of the placenta, particularly its hormonal effects, and how these might be replicated in a synthetic environment. The discussion highlights that while neonatal intensive care currently relies on incubators, a synthetic placenta could represent a significant advancement in care for premature infants. The technology remains experimental, and future iterations are expected to incorporate more features of natural placental function.

Scientists have been able to bring fetal lambs to term using plastic bags to replace their normal amniotic sacks and a bit of plumbing to replace the placenta. They hope to do this with premature humans eventually.

Not sure about the placental replacement part since I thought the placenta had some hormonal effects on the fetus, but maybe that's only at earlier stages or for the mother.
 
Biology news on Phys.org
For premies, maturing within the sack or outside, the placenta isn't available in either case.
This is not for embryonic development to maturity, as that I would think would be years away.
Even the "placental fluid" is not much more than a saline solution for the sack.

This does not make sense to me, can you please explain? They are going to supplant/replace the placenta. My take on it, anyway.

Presently neonatal intensive care for premature is through an incubation unit.

So it would be a step forward I believe, to have a placenta type care unit.
As this is a prototype and experimental, it's features would change in future use for humans, with more placental features.
 
Haha haha yes one step closer to:woot: !... Um oh I er yes that is very interesting:wink:
