Ovaries printed in 3D to give new hope to women

It's a discovery that can spark the hope of hundreds of women scientists at Northwestern University. The latter created mouse ovaries printed in 3D and were thus able to give birth.

3D prints to give life back

Researchers at Northwestern University in Chicago, Illinois, USA, supported by the Mc Cornick School of Engineering, have done what may be considered a big step for medicine.

The project of the two entities was to create ovaries printed in 3D, to implant them in a mouse. At the end of the transplant, the researchers were able to note that the new ovaries increased the level of hormones produced by the mouse. and by incidence, the fertility of mice.

The tour com force of this experience is that if the program is a success for mice, it can apply to women. What does this change concretely? For women who could not have children, for example because of early cancersor for women who are no longer able to procreate, a second chance is possible.

Ovaries printed in 3D operational in "10-15 years"

However according to one of the main people in charge of the study, Teresa K. Woodruff, "This will not happen for at least 10 or 15 years." To get the most out of the process, scientists will have to make an egg using the woman's stem cells and then produce sex hormones. Finally, they will need to insert them into a functional ovarian follicle to stimulate the cycle.

So far, the university has stored 375 ovarian tissue in human patientsin 98 participating centers in the country to help these women to reproduce later.

This program is in parallel with other projects. This is for example the case of the Atlanta-based Prelude start-up valued at $ 200 million. The company plans to delay the biological clock of women allowing them to have children until old age. If the start-up has no rights to practice in the United States, the firm has already been able to create young eggs in Canada and Japan.
