Extent of immunostaining for MMPs and TIMPs during the estrous cycle. Bar graphs represent mean ± SEM immunostaining index levels (scores of 0-4) for (A) MMP-2, (B) MMP-9, (C) MMP-14, (D) TIMP-1, and (E) TIMP-2. Index indicates overall extent dark red stained cells across the ovarian cross section in the different stages of estrous in Siberian hamsters. Groups with different letters are significantly different (p < 0.05).
