Figure 1.
A schematic illustration of the proposed regulation and roles of thecal cell-derived STC-1 in granulosa cells and luteal cells in the developing follicle. Demonstrated roles are shown with solid arrows, postulated roles are shown with dashed arrows. cAMP, cyclic adenosine monophosphate; IGF, insulin-like growth factor; PKA, protein kinase A; ROS, reactive oxygen species; STC-1, stanniocalcin-1.
