摘要:

卵巢组织玻璃化冷冻及移植技术是保留生育功能的重要手段,尤其适用于需要接受性腺毒性治疗的年轻肿瘤女性和青春期前儿童。该技术涉及多个影响冷冻及移植效果的因素。在冷冻保护剂的选择上,成分、浓度及平衡时间均对冷冻效果有显著影响。卵巢组织的加工处理和冷冻载体的选择也是影响冷冻移植效果的关键因素之一。在解冻复苏过程中,需精细控制冷冻保护剂的去除速率,以防细胞受损。移植部位的选择可根据患者的实际需求决定。移植初期的缺血缺氧和氧化应激是导致卵泡丢失的重要因素,可通过使用促血管生成因子、干细胞、抗氧化剂等改善移植效果。除此之外,患者年龄、移植次数、妊娠方式等临床因素也会影响移植后的妊娠率。这些因素为优化卵巢组织冷冻移植的成功率提供了科学依据和实践指导,为未来的研究和临床实践提供了新的思路和方向。

Abstract:

Ovarian tissue vitrification and transplantation techniques are crucial for fertility preservation, especially for young women with the cancer requiring gonadotoxic treatments and for prepubertal children. This technique involves multiple factors that affect the outcomes of cryopreservation and transplantation. In terms of cryoprotectant selection, the composition, concentration and equilibration time have significant effects on the freezing outcome. The processing of ovarian tissue and the choice of freezing carrier are also crucial factors influencing the success of cryopreservation and transplantation. During thawing and recovery, the removal rate of cryoprotectants must be carefully controlled to prevent cellular damage. The choice of transplantation site can be determined, based on the patient′s actual needs. Ischemia, hypoxia and oxidative stress during the initial period after transplantation are important factors leading to follicular loss, which can be improved by the use of angiogenic factors, stem cells, antioxidants, and other interventions. Additionally, clinical factors such as the age, number of transplantations and mode of conception can also impact the pregnancy rates following transplantation. These factors provide a scientific basis and practical guidance for optimizing the success rate of ovarian tissue cryopreservation and transplantation, offering new insights and directions for future research and clinical practice.
