Histological study of rat ovaries cryopreserved by vitrification or slow freezing and reimplanted in the early or late postmenopausal stage.
PURPOSE To compare two rat ovary cryopreservation techniques (vitrification vs. slow freezing) and two postmenopausal stages (early vs. late) with regard to graft take. METHODS Thirty-three Wistar rats were submitted to bilateral oophorectomy. One ovary was submitted to histological analysis while the other was cryopreserved by slow freezing or vitrification. The cryopreserved ovary was thawe...
متن کاملRestoration of ovarian function after orthotopic (intraovarian and periovarian) transplantation of cryopreserved ovarian tissue in a woman treated by bone marrow transplantation for sickle cell anaemia: case report.
Ovarian function after orthotopic transplantation of cryopreserved ovarian tissue has been restored in women with malignant disease. Here the techniques are adapted for a non-cancer patient. In 1999, right oophorectomy was performed in a 21 year old woman before chemotherapy, prior to bone marrow transplantation. Ovarian cortex was frozen, according to a strict protocol. After thawing, ovarian ...
متن کاملIn vitro development of secondary follicles from cryopreserved rhesus macaque ovarian tissue after slow-rate freeze or vitrification.
BACKGROUND Ovarian tissue cryopreservation is the only option for preserving fertility in prepubertal girls and cancer patients requiring immediate treatment. Following ovarian tissue cryopreservation, fertility can be restored after tissue transplant or in vitro follicle maturation. METHODS Macaque (n= 4) ovarian cortex was cryopreserved using slow-rate freezing (slow freezing) or vitrificat...
متن کاملO-21: Differential Expression and Epigenetic Pattern of HOX Family Genes in Cumulus Cells of Mature MII Oocytes from Patients with Polycystic Ovary Syndrome
Background Ovarian tissue cryopreservation represents a promising strategy to preserve the ovarian function in cancer patients. It is usually performed by slow freezing/rapid thawing (SF/RT). Recent studies emphasize an ultrarapid cryopreservation procedure, vitrification/warming (V/W), since it might prevent damages due to ice crystal formation. Comparative studies between the cryopreservation...
متن کاملRole of endocrine disrupting chemicals on the tissue levels of AhR and sex steroid receptors in breast tumours
Breast cancer affects Iranian women at least one decade younger than their counterparts in othercountries and the incidence of breast fibroadenoma is growing in the last two decades in Tehran. Thisstudy aimed to compare the AhR levels in premenopausal breast cancer and breast fibroadnemo withappropriate normal groups. Possible associations of AhR with lifestyle and reproductive risk factorsand ...
