Artificial wombs kept premature lambs alive

A “biobag” womb has successfully kept lambs born prematurely alive, improving hope for future premature human babies.


The current incubators used for premature babies can damage the lung development of the newborns. This artificial womb would hopefully provide a space where premature babies can develop more naturally. The umbilical cord is attached to a machine.

Currently, humans born at 23 weeks only have a 15% chance of survival, and researchers greatly hope this “womb bag” can be developed to increase chances of survival in these cases. The lambs were equivalent to 23-week old humans in terms of development. Many lambs who have been through this process have survived. Although more research needs to be done, as Professor Colin Duncan of the University of Edinburgh said, “This study is a very important step forward.”
