Figure 4From: Ovarian matrix metalloproteinases are differentially regulated during the estrous cycle but not during short photoperiod induced regression in Siberian hamsters (Phodopus sungorus)Representative MMP and TIMP protein immunodetection during the estrous cycle in Siberian hamsters. Ovarian immunohistochemical staining (dark red stain on purple/blue hematoxylin background) for all MMPs and TIMPs. (A-D) MMP-2 immunostaining, (E-H) MMP-9 immunostaining, (I-L) MMP-14 immunostaining, (M-P) TIMP-1 immunostaining, and (Q-T) TIMP-2 immunostaining. Insets show negative control immunostaining (no primary antibody present).Back to article page
