The capacity of ovarian cells of the postnatal rat to reorganize into histiotypic structures.

Cell-reorganization experiments in vitro were performed with dissociated rat ovaries at different ages of postnatal development, namely newborn, 8-10, 15-22, and 90-day-old. Ovarian cells consistently aggregated into follicularlike structures. Follicular organization ion vitro is comparable to the ovarian histology of the respective age. The histogenic properties conserved by ovarian cells are considered to be related with the morphogenetic processes steadily occurring in the ovary.
