OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.

The maturation of functional eggs in the ovaries is a critical process during reproduction. However, the underlying mechanisms driving follicle growth remain enigmatic. In this talk, I will present new findings that the contractile surface cells of follicles can exert compressive stress to impact oocyte signalling and follicle growth, and regulate follicle growth competition in assemblies. I will also report the role of cell death and interfacial tension in driving critical behavior of luminogenesis during follicle development. Our studies highlight the importance of mechanical stress and hydraulics in ovarian dynamics, and the need of a biophysical approach to understand these fundamental stage of reproduction.
