The effects of in vivo hormonal sensitization on the competence of uterine stromal (US) cells to decidualize in vitro were assessed. In vitro differentiation of uterine stroma isolated from Day 4 pregnant rats, sensitized to respond to a decidual stimulus, was compared to that in nonsensitized immature, castrated or cycling rats. The initiation of in vitro decidualization--as monitored by the expression of the decidual markers desmin and laminin in rat US cells--was independent of the hormonal status of the animal from which the cells were isolated and occurred in the absence of serum in the medium. Differentiation was accelerated in high-density cultures where contact inhibition suppressed proliferation and decreased the extent of cell growth. The extent to which in vitro decidualization imitates in vivo stromal cell differentiation was assessed by comparing decidualization in the rabbit, a species with only a limited decidual cell response, and in the rat. US cells isolated from nonpregnant rabbits differentiated in vitro by expressing laminin, but not desmin. Indirect immunofluorescence of frozen uterine sections from pregnant and nonpregnant rabbits validated in vitro differentiation as a faithful reflection of the in vivo program of decidualization. Although the program of US cell differentiation may vary between the species, initiation of differentiation in vitro appeared to be independent of hormonal preparation in vivo for both the species examined.
