- Abstract: The mouse blastocyst implants within an antimesometrial uterine chamber and the embryo later attaches to the mesometrial uterine wall where the placenta is formed. This event causes the obliteration of the uterine lumen at the mesometrial region of the uterus. Later on, the uterine lumen is reformed in the antimesometrial region. Although no embryo is present in pseudopregnancy, the uterine lumen becomes occluded by the development of the mesometrial decidua. This study describes the development of a new uterine lumen in mouse bearing deciduoma. The deciduoma was induced by injecting 50µL of almond oil into the uterine lumen on day 4 of pseudopregnancy. Animals on days 9,10 and 11 of pseudopregnancy received an ip injection of 3H-thymidine diluted in PBS. Control animals received PBS. Samples were collected after 1 hour, processed by embedding in paraffin. Sections were covered by nuclear emulsion, and photographically developed. A qualitative radioautographic analysis showed that epithelial gland cells placed at the antimesometrial region were able to incorporate 3H-thymidine. The distribution of silver grains suggests that the new lumen was rebuilt by the proliferation of glandular epithelial cells and later fusion of these glands. Moreover, epithelial cells that lined the interimplantation sites migrated to these sites
