The lipid metabolism of granulosa cells plays a pivotal role in the development of goose follicles. However, the mechanisms by which lipid droplet-associated proteins regulate lipid droplets and influence cellular lipid metabolism remain poorly understood. To address this, our study systematically identified lipid droplet-associated proteins in goose follicular granulosa cells and analyzed these proteins at five distinct time points, in both pre-hierarchical granulosa cells and hierarchical granulosa cells, thereby obtaining relevant information on lipid droplet-associated proteins.
