Mean ± SEM volume of the granule cell layer (GCL) and the hilus (mm3) in female ovariectomized rats from Experiment 1 and 2 exposed to estradiol (E2), the GPER agonist G1, and the GPER antagonist G15.

There were no significant differences between treatments observed in the volume of the GCL or hilus.Mean ± SEM volume of the granule cell layer (GCL) and the hilus (mm3) in female ovariectomized rats from Experiment 1 and 2 exposed to estradiol (E2), the GPER agonist G1, and the GPER antagonist G15.各处理组在颗粒细胞层（granule cell layer, GCL）与门区（hilus）的体积上均未观察到显著差异。本研究实验1与实验2中，经雌二醇（estradiol, E2）、G蛋白偶联雌激素受体（GPER）激动剂G1及GPER拮抗剂G15处理的雌性去卵巢大鼠，其GCL与门区的体积均值±标准误（单位：mm³）。
