Researchers in Barcelona are attempting to “trick nature” by creating an artificial womb for terribly untimely infants after assessments on animals saved foetuses alive for 12 days.
Their artificial placenta prototype recreates a protecting setting with a translucent container product of biocompatible materials inside which the foetus’ lungs, intestines and mind can proceed to develop.
It is linked to an amniotic fluid circulation system that maintains the foetus remoted from exterior stimuli however accessible for ultrasound controls and monitoring.
Babies born after six months of being pregnant or much less are thought-about extraordinarily untimely with a excessive threat of demise or incapacity. The World Health Organization’s newest figures present that round 900,000 such infants died worldwide in 2019.
“We try to develop a system that allows us to keep a foetus outside its mother but still in the foetal conditions: that it continues to breathe through the umbilical cord … that we can feed it through the umbilical cord, that it lives surrounded by fluid at a constant temperature,” mission head Eduard Gratacos instructed Reuters.
He leads a staff of 35 from BCNatal medical analysis centre – a fusion of the maternal-fetal medication and obstetrics departments of two Barcelona hospitals – and Fundacion La Caixa, a non-public organisation funded by Caixabank.
‘Extremely delicate’
The staff has carried out pre-clinical research with lambs, the place they achieved 12-day foetus survival, and plans to additionally check with pigs earlier than proposing a human trial in a couple of years.
“The highly-complex project spans many different specialties of medicine and requires engineers of different types. It’s a challenge, it’s extremely delicate to achieve this, to trick nature to make this possible,” Gratacos stated.

Among a couple of such initiatives worldwide, one group of scientists on the Children’s Hospital of Philadelphia managed to preserve animal foetuses alive for 28 days.
Kelly Werner, assistant professor of paediatrics at Columbia University, instructed the Science Media Centre the Spanish staff’s optimistic outcomes have to be rigorously examined in medical trials on people to verify for security and unwanted effects.
“Although it is an exciting development, the artificial placenta is not intended to replace a natural placenta,” Werner stated. “That is, despite these advancements, we still should make every effort to support maternal health and decrease risk factors that lead to preterm birth.”
