Transmission electron microscopy analysis of ultrastructural changes in the uterine stromal matrix in response to E 2 treatment. Representative TEM micrographs of the endometrial stroma of animals administered E2 (40 μg/kg) at the indicated time points prior to tissue collection. Micrographs shown are representative of typical observations from a total of 54 to 72 micrographs analyzed from 4-5 animals per time point; C = Collagen, S = Stromal cell, scale bar = 0.5 μm.
