Female mice were able to give birth to healthy babies through 3-D printed ovaries, according to a study published in Nature Communications.
According to the study, the pups were born through natural mating and the moms were able to nurse their young. 3-D printed ovaries were transplanted into mice whose ovaries had been removed. The 3-D printed ovaries consisted of scaffolds, which supported follicles. The scaffolds were made of gelatin ink so they were microporous and bioactive. The follicles ovulated mature eggs.
Hormones were not given to the animals.
Scientists hope this research can lead to further developments in human applications.
