Recently, new breakthroughs have been made in the medical field. American scientists have developed artificial uterus to allow premature lambs to survive and continue to develop for up to one month. The study was published in the journal Nature News.
It is understood that this new study comes from the Fetal Diagnosis and Treatment Center of the Children's Hospital of Philadelphia, USA. The researchers used plastic to make a container similar to the uterus, and filled it with a unique laboratory-produced liquid and salt. This system effectively Imitated the situation in the womb. Because the developing lungs are unable to breathe oxygen in the atmosphere, this step allows the developing fetus to breathe the artificial amniotic fluid that flows into and out of the bag, and it also contains all the necessary nutrients and growth factors for healthy development. In addition, the artificial uterus is also connected with a special tube of artificial uterus, and a daily amount of "amniotic water" is injected to ensure that the lambs in the life are freshly supplied.
In the study, the researchers tested eight premature lambs, five of which were equivalent to 23 weeks of premature human size, and three more gestational weeks. The researchers placed the premature lamb in a fluid film bag and attached the umbilical cord. To the external oxygenator that mimics the mother's placenta. This allows the fetus to use its own heart to deliver blood to the body and outside the uterus without the need for external help.
The premature lamb is sealed in a bag, isolated in a sterile environment and protected from stress and light for up to 28 days, during which time they remain healthy, naturally develop, breathe normally, open their eyes , moving, and even growing wool, did not show complications.
Researchers are currently working to tweak the system, including reducing its size to fit a human baby, usually one-third the size of a lamb. In addition, the research team also began discussions with the US FDA, hoping to conduct human experiments within three to five years. They claim that they have no intention of replacing the human uterus or challenging the embryo's survival limits, and only hope to explore better ways to care for prematurely born fetuses.
