PURPOSE: create a 3-Dimensional artificial human ovary to mature human oocytes.
METHODS: theca and granulosa cells were isolated from antral follicles of reproductive-aged women, seeded into micro-molded gels and self-assembled into complex 3D microtissues. Immunohistochemistry and live-dead staining confirmed theca cell identity and cellular viability at one week respectively. Placement of granulosa cell spheroids or cumulus-oocyte complexes into theca cell honeycomb openings resulted in creation of an artificial human ovary. Oocytes from this construct were assessed for polar body extrusion.
RESULTS: theca and granulosa cells self-assembled into complex microtissues, remaining viable for one week. At 72 h after artificial human ovary construction, theca cells completely surrounded the granulosa spheroids or COCs without stromal invasion or disruption. Polar body extrusion occurred in one of three COCs assessed.
CONCLUSIONS: an artifical human ovary can be created with self-assembled human theca and granulosa cell microtissues, and used for IVM and future oocyte toxicology studies.
