title: Age-dependent sensitivity of basal cells in mouse vaginal epithelium towards the diferentiating action of estrogen.
abstract: Following ovariectomy, the vaginal epithelium of the mouse is reduced to two layers of cells, the basal layer that constitutes the germinative compartment and surface layer. Under estrogenic influence, this tissue undergoes keratinization at the expense of asal cell only. The initially superficial cells are progressively sloughed, without taking part in the cornification process. We have shown previously that within the first 12 hours after estrogen administration (that is, before any change in mitotic activity is detected) an intermediate layer of cells is formed. Thurs, a migratory process is induced, which leads to a very rapid redistribution to basal cells into two layers...
