OBJECTIVES Adipose tissue contains a population of multipotent adipose stem cells (ASCs) that form tumor stroma and can promote tumor progression. Given the high rate of ovarian cancer metastasis to the omental adipose, we hypothesized that omental-derived ASC may contribute to ovarian cancer growth and dissemination. MATERIALS AND METHODS We isolated ASCs from the omentum of three patients w...
Background Although ovarian tissue cryopreservation and transplantation is used for fertility preservation in patient undergoing cytotoxic treatments but obtaining good quality oocyte is still a debate. Xenotransplantation has been introduced as a reliable technique for better understanding of the transplantation conditions, but to achieve healthy embryos, the quality of obtained oocytes need t...
Many investigations have utilized techniques for culturing ovarian tissue or isolated follicles in vitro. Whole ovaries from fetal or neonatal rodents have been incubated in organ culture systems. This has been utilized to understand the sequence of follicle formation and its hormonal requirements, activation of quiescent follicles, follicular growth and development, and acquisition of steroido...
bleomycin (blm)as an anti-cancer agent causes tissue toxicities through dna damaging and cell deaths. the aim of this study was to investigate the effects of thymol against genotoxicity and anti-proliferation induced by blm in normal human lymphocytes and ovarian cancer cells.peripheral blood samples were collected from human volunteers and were incubated with thymolat different concentrations ...
BACKGROUD Ovarian transplantation is a useful method for preserving the fertility of young women with cancer who undergo radiotherapy and chemotherapy. Follicle-stimulating hormone (FSH) is use to protect transplanted ovarian tissues from ischemia injury through promoting revascularization after transplantation, but the side effect of high level FSH is ovarian overstimulation leading to substan...
In recent years it has become evident that a leukocyte-cytokine network contributes to the paracrine regulation of ovarian function. The objectives of this study were to examine the presence of a potent lympho-haemopoietic cytokine, granulocyte-macrophage colony-stimulating factor (GM-CSF), in tissues and fluids from human ovaries. In a prospective study, follicular fluid and plasma were collec...
The objective of this study was to explore the feasibility and methods of screening the residual normal ovarian tissue adjacent to orthotopic ovarian carcinomas in nude mice. Human epithelial ovarian cancer cells (OVCAR3) were subcutaneously implanted for a tumor source and ovarian orthotopic transplantation. The cancer tissue, proximal paraneoplastic tissue, middle paraneoplastic tissue, remot...
