Early and natural embryonic death in Lagostomus maximus: Association with the uterine glands, vasculature, and musculature

In mammals, pregnancy requires diverse sex hormones, growth factors and cytokines, among others, for promoting uterine remodeling to favor implantation, placentation, and embryo/fetus survival and growth.
