Effects of euthyroid HT on endometrial pinopodes in mice. A Representative SEM images of the pinopodes on the apical surface of the eutopic endometrium luminal epithelium during the window of implantation at magnification × 5000, × 10,000. Red arrows indicate endometrial pinopodes. B A histogram of the number of pinopodes for each microscopic field. Data were recorded as the mean ± SEM, n = 3, ^***p < 0.001, vs. Con
