An artificial uterus that saved the life of a lamb may be used in humans A scientists team from the Children's Hospital of Philadelphia, PA, was able to keep alive premature lambs in an innovative plastic bag. This is a device that simulates the conditions of the maternal uterus, whose tests have gave very successful results. In fact, a research published by Nature Communications magazine that uses data from the experiments, point pout that the scientists were able to keep alive premature lambs for four weeks. Although it is true that this had been previously tried, this is the first time that was successful. Unlike earlier tests that achieved to keep alive the animals just for 60 hours, the tests for this new device were capable to reach 28 days of survival. According to the leader of the scientists team, the goal of the plastic bag is not to replace an uterus during the first pregnancy stages, but the purpose is to develop a mecanism to afford premature babies be treated. Thus, the objective is to produce the required conditions after the premature birth, in order to stabilize the newborn. In fact, first tests in humans are planned to be developed in a couple of years.
