You can 3D-print pretty much anything these days. Need a base on the Moon? A robot can 3D-print one for you. How about an entire human heart? Yep, youre covered. You can even, somewhat anemically, 3D-print cheese into rather pointless structures.

A team led by the Northwestern University of Chicago has defined the bar pretty high, though. As revealed in a Nature Communications study, theyve managed to 3D-print ovary structures for mice.

Printed utilizing a gelatin ink, these synthetic ovaries were planted into female mouse after they had their actual ovaries removed. Not merely were they able to ovulate, but they likewise managed to give birth to healthy puppies that were nursed to full health.

The ovaries, which are also important hormone control centers, continued to keep hormone degrees within the mother mouse at normal levels. For all intents and purposes, their performance was indistinguishable from the real deal.

Plenty of women have difficulties conceiving after theyve suffering from an ailment or cancer especially cancer or after theyve undergone medical treatment that has in some way damaged their ovaries. This type of ovarian harm can also severely impede hormone production, which is particularly risky for girls who are about to go through puberty.

This groundbreaking study shows that at some phase in the not-too-distant future, synthetic 3D-printed ovaries may be able to be implanted into women with these issues. Organ donors will no longer be required.

Using bioengineering, instead of transplanting from a cadaver, to create organ structures that function and restore the health of that tissue for that person, is the holy grail of bioengineering for regenerative medicine, co-author Teresa Woodruff, a reproductive scientist and director of the Womens Health Research Institute at Feinberg, said in a statement.

The ink choice was key here. Gelatin, made from broken-down collagen, is rigid enough to be manipulated during surgery, but porous enough to allow it to properly interact with the mouses biology. At a certain temperature, the team found that they could print complex, multi-layered structures with it, and eventually this led them to erecting a synthetic ovary.

Although it required decades of research to be able to 3D-print these ovary scaffolds in the first place, the team uncovered plenty of new information along the way. For instance, it wasnt known until just now that the precise geometry of the ovary has a huge effect on whether or not the ovarian follicles the supporting cells that encase an immature egg cell will become viable within the ovary.

All in all, the results of the study represents a huge leap forward in reproductive science.
