Cystogenesis of antral follicles induced by dehydroepiandrosterone (DHEA) stimulates mast cell proliferation and maturation in the house rat (Rattus rattus) ovary.

Abstract:

:Mast cell dynamics has been studied in relation to cystogenesis of ovarian follicles in the house rat. Immature rats were injected (s.c.) daily with DHEA (6.0 mg/100 g body weight) and were sacrificed on the day 8, 16 and 24 of the start of treatment. Ovarian sections of the treated rats had majority of the antral follicles undergoing atresia or in early stages of cystogenesis. Completely developed cysts were evident from the ovarian surface after 24 days of daily treatment. Treatment for 8 days resulted in significant increase in the number of alcian blue-positive ovarian mast cells. Ovaries after 16 days of DHEA treatment showed no marked change with regard to the number of total mast cells per unit area and staining characteristics. However, a significant rise in ovarian mast cell counts was recorded after 24 days of treatment and most of the cells contained safranin-positive red granules. This increase was attributed due to the increase in their number in medulla and stroma around the cystic follicles.
