Discussion Overview

The discussion revolves around the scientific advancements in using artificial environments, specifically plastic bags, to support the development of fetal lambs and the potential implications for premature human infants. The focus includes the feasibility of replicating placental functions and the implications for neonatal care.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants highlight that scientists have successfully brought fetal lambs to term using artificial methods, raising hopes for similar applications in humans.
  • One participant questions the viability of replacing the placenta, suggesting it may have hormonal effects that are crucial for fetal development.
  • Another participant clarifies that for premature infants, the placenta is not available regardless of whether they mature inside or outside the womb.
  • There is a suggestion that the artificial environment may not be intended for embryonic development but rather for supporting premature infants, which could be a significant advancement in neonatal care.
  • A participant expresses the belief that a prototype with more placental features could evolve from current experimental setups.

Areas of Agreement / Disagreement

Participants express differing views on the role and importance of the placenta in this context, with some uncertainty about the implications of its replacement. The discussion remains unresolved regarding the specifics of how placental functions might be replicated.

Contextual Notes

There are limitations in understanding the full implications of replacing the placenta, including potential hormonal effects and the specific requirements for fetal development that may not be addressed by current artificial methods.

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:
