Expression characteristics of MMP-2 and MMP-9 in guinea pig ovaries during the estrous cycle
“Expression characteristics of MMP-2 and MMP-9 in guinea pig ovaries during the estrous cycle”, vol. 14, pp. 17329-17340, 2015.,
We investigated the expression characteristics of matrix metalloproteinases (MMP)-2 and MMP-9 in the ovaries of normal adult guinea pigs during the estrous cycle. The estrous cycle was classified according to the appearance of the vaginal orifice and by vaginal exfoliated cell smears. Guinea pigs that had experienced at least two normal estrous cycles were selected. Ovaries were collected from guinea pigs at proestrus or metestrus (N = 6).
