Postnatal development of the Mongolian gerbil uterine glands.
The development of gerbil uterine glands has been described. Gland formation starts about day 6 postnatally (p.n.). At day 10 p.n. the glandular lumen contains already some fluid, and the glandular cells are in an activated state. The apical shape of the glandular cells depends mainly on the width of the lumen. Secretory vesicles in early developmental stages are electron-lucent. As sexual maturity is reached, secretory granules become electron-dense. This change in secretory granular structure indicates a change in the quality of uterine gland fluid.
