3D-printed ovaries successfully restore mouse's fertility in 'holy grail of bioengineering'
ABCScientists have used 3D-printed ovaries to successfully restore fertility for the first time in what they call "the holy grail of bioengineering for regenerative medicine". A female mouse's ovaries were removed and replaced with 3D printed bioprosthetic ones using gelatin as the "ink" and using eggs from different mice — enabling it to ovulate, conceive pups and give birth, the United States researchers said. "The pups were supported by the mother's milk — and the pups were able to give birth or sire pups of their own, so they were healthy through adulthood and fertile," co-lead researcher Assistant Professor Monica Laronda, from Northwestern University and the Ann and Robert H Lurie Children's Hospital, said. She said it was also hoped human bioprosthetic ovaries could be used to help restore fertility to women with premature ovarian failure.
