摘要: 目的  探索天然冷冻保护剂L-脯氨酸(L-proline, L-pro)冷冻保存人卵巢组织移植的有效性,并与传统冷冻保护剂二甲基亚砜(dimethyl sulfoxide,DMSO)进行比较。方法  采用慢速冷冻方法,将10例患者的卵巢皮质组织分别用基于DMSO和L-pro的冻存液进行冷冻保存,复苏后移植于已去势雌性裸鼠体内;对照组只去势。移植21 d后取出卵巢组织移植物进行卵泡计数,并检测血清中促卵泡刺激素(follicle-stimulating hormone, FSH),雌二醇(estradiol, E2)和抗米勒管激素(anti-Müllerian Hormone, AMH)的浓度。结果  L-pro组静止卵泡数量显著高于DMSO组(P=0.042),而2组在生长卵泡数量及总卵泡数量方面差异无统计学意义(P均>0.05)。2个实验组各项血清激素水平较对照组均显著改善(P均<0.05),且L-pro组与DMSO组间各项血清激素水平差异无统计学意义。结论  L-pro作为冷冻保护剂在卵巢组织冻存异种移植中卵泡保护和激素恢复的效果不亚于传统的冷冻保护剂DMSO。为卵巢组织冻存的冷冻保护剂优化提供了新的思路和实验依据,未来仍需进一步深化机制研究和长期功能的研究。

Abstract: Objective  To evaluate the efficacy of the natural cryoprotectant L-proline (L-pro) in human ovarian tissue cryopreservation and transplantation, and to compare it with the conventional cryoprotectant dimethyl sulfoxide (DMSO).Methods  Ovarian cortical tissues obtained from ten patients were cryopreserved using a slow-freezing protocol with either DMSO-based or L-pro-based cryoprotective solutions. After thawing, the tissues were xenotransplanted into ovariectomized female nude mice, while the control group underwent ovariectomy only. Twenty-one days after transplantation, grafts were retrieved for follicle counting, and serum levels of follicle-stimulating hormone (FSH), estradiol (E2), and anti-Müllerian hormone (AMH) were measured.Results  The number of quiescent (primordial) follicles was significantly higher in the L-pro group than in the DMSO group (P=0.042), whereas no significant differences were observed in the number of growing follicles or total follicle counts between the two groups (all P> 0.05). Serum hormone levels in both experimental groups were significantly improved compared with the control group (all P<0.05), with no significant differences between the L-pro and DMSO groups.Conclusion L-pro, as a cryoprotectant, demonstrates comparable efficacy to DMSO in preserving follicular integrity and restoring endocrine function following ovarian tissue cryopreservation and xenotransplantation. These findings provide a novel perspective for optimizing cryoprotective agents in ovarian tissue preservation, although further studies are needed to elucidate the underlying mechanisms and long-term functional outcomes.
