Figure 5From: Ovarian matrix metalloproteinases are differentially regulated during the estrous cycle but not during short photoperiod induced regression in Siberian hamsters (Phodopus sungorus)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).Back to article page
