Langerhans cells in murine vaginal epithelium affected by oestrogen and topical vitamin A

Langerhans cells vary in their morphology and distribution in the vaginal epithelium of ovariectomized mice stimulated to hyperplasia and keratinization by oestrogen. When the stratum corneum was removed by topical vitamin A application, the shape and distribution of Langerhans cells were unaffected. It was concluded that Langerhans cell morphology and distribution depend on the configuration of the lower strata of the epithelium and not on the presence of a stratum corneum.
