title: [New findings on the embryogenesis of the uterus].
abstract: In this study including twelve embryos, aged 4 to 8 weeks, and twenty-one fetuses between 9 and 25 weeks, and a group of five still-born fetuses between 25 and 40 weeks, the authors used conventional techniques of histological preparations and immuno-chemistry according to the BSA technique (biotin-streptavidin with peroxidase labelling), in order to demonstrate that the uterus presents a "dual embryogenesis". The endometrium with its stroma and the transition zone endometrium-myometrium have a coelomic origin. The myometrium with the common connective tissue derive from primary mesenchyma. According to the authors, the "dual embryology" of the uterus, would permit simplifying the taxonomy of the histogenesis of uterine tumors.
