-
Northwestern researchers have developed the ability to 3D print artificial ovaries that can support follicle growth and maturation. The scaffold design and porosity can be easily manipulated by varying the extracellular matrix makeup and the method by which the ovary is printed, ultimately creating the optimal biomimetic scaffolds. The structure can also be modified post-printing to enhance and tailor mechanical properties in the ovary. Once cells are seeded onto the construct and cultured, the 3D printed ovaryexhibits long-term support for follicle health. Mice with transplanted 3D printed ovaries gave birth to two generations of healthy pups, exhibiting the ability of the ovaries to support endocrine function and promote oocyte development. Current strategies for gonadal dysfunction, which include egg banking, embryo banking, and in vitro oocyte maturation, are time-consuming and unsuitable for hormone-responsive cancer patients and pre-pubertal patients. Further, they do not provide endocrine support. Northwestern researchers have created highly customizable 3D printed artificial ovaries which can offer both restoration of fertility and endocrine function.
