title: Autograft of vitrified mouse ovaries using ethylene glycol as cryoprotectant.
abstract: Ovaries from 8 to 10-week-old N MRI mice were vitrified using RPMI solution containing 30% (W/V) ficoll 70, 0.5 M sucrose, 10.7% (V/V) acetamide and 40% (V/V) ethylene glycol (EGFS40%), and were stored in liquid nitrogen. After warming at 25 degrees C in 1 M sucrose solution and equilibration with RPMI medium, the vitrified and fresh ovarian tissues were autografted intraperitoneally. After one and two estrus cycles the animals were sacrificed and the recovered grafts were examined histologically. Five days after transplantation the vitrified ovaries they were invaded by fat and fibrous cells and the large preantral and antral follicles were degenerated. At 11 days postgrafting the stroma was devoid of necrotic cells and contained normal primordial and primary follicles, suggesting that the vitrification is a simple, useful and efficient procedure for cryopreservation of murine ovarian tissues.
