DEVELOPMENT STAGE
TRL-4 Prototype Validated in Lab: Self-assembly and follicle encapsulation have been demonstrated in a laboratory setting.
BACKGROUND
The ovary is a complex organ composed of follicles developing within a dynamic stromal microenvironment that plays an essential role in regulating follicle growth, maturation, and overall ovarian function. Despite the importance of stromal–follicular interactions, existing ovarian culture systems often fail to fully integrate these subcompartments, limiting their ability to accurately model native ovarian physiology. Prior studies have demonstrated that isolated follicles co-cultured with ovarian stromal feeder cells exhibit enhanced growth, underscoring the critical role of the stromal environment in supporting follicle development. More physiologically relevant ovarian models are therefore needed to better capture the cellular interactions that drive ovarian biology.
ABSTRACT
Northwestern researchers have developed the micro-ovary, a three-dimensional, self-assembled ovarian model that mimics native in vivo physiology on a microscale. It integrates an intact follicle with an engineered stromal microenvironment, enabling dynamic physical, mechanical, and paracrine interactions. Robust validation in laboratory settings using both murine and rhesus macaque cells confirms its capability to encapsulate and support follicle growth. This platform offers significant potential for studies in ovarian biology, fertility treatment development, and reproductive medicine.
