Introduction: Chemotherapy has cytotoxic effect that induces follicular damage and abnormal folliculogenesisleads to ovarian failure. Two crucial growth factors in abnormal folliculogenesis, Growth Differentiation Factor-9 (GDF-9) and Kit-Ligand, will be disrupted and affect follicular development. In this study, we evaluate whether bone marrow transplantation (BMT) has a role on oocyte-granulosa cell interaction by analyzing GDF-9 and Kit-Ligand expressions and also follicular development by analyzing primordial, primary, secondary and graafian follicles of cisplatin-induced ovarian failure in rat. Material and method: Forty eight rats were divided into three groups: control, cisplatin and cisplatin+BMT. Ovarian failure was induced by administration of intraperitoneal cisplatin 5 mg/kg body weight for 1 week. BMT 2 × 107 cells were injected through rat tail vein after cisplatin administration. Bone marrow was isolated from rat femur and characterized by CD44(+), CD45(-), CD105(+). Immunohistochemistry examinations for ovarian GDF-9, Kit-Ligand and follicle development evaluation were performed after 2 weeks of BMT injection. Results: The expressions of Kit-Ligand among three groups by ANOVA were significant different (p=0.00), whereas by Post Hoc: cisplatin group lower than control group (p=0.00); cisplatin+BMT group higher than cisplatin group (p=0.00); and no significant different between control group and cisplatin+BMT group (p=0.955). The expressions of GDF-9 by Kruskal Wallis showed significant different (p=0.00) among three groups whereas cisplatin+BMT group higher than cisplatin group and control group. In cisplatin+BMT group the number of primordial, primary, secondary and graafian follicles were higher than those in cisplatin group; but were lower than those in control group (p=0.000). Positive Paul Karl Horan (PKH) labeling was seen in cisplatin+BMT group only. Conclusion: In cisplatin-induced ovarian failure in rat, bone marrow transplantation may improve oocytegranulosa cell interaction and follicular development.
