摘要:

目的: 探索利用玻璃化冻存新技术保存肺癌手术标本,复苏后用于类器官构建的可行性。方法: 选择2024年7—8月在首都医科大学附属北京胸科医院确诊的12例肺癌患者手术切除的肿瘤组织作为研究对象。肿瘤组织由病理医师取材后立即置于组织保存液中,4℃条件下保存运输,2h内完成样本处理。每例样本均分为3份,每份大小约为0.5cm3。一份直接用于类器官构建,另外两份采用玻璃化冻存技术保存于气相液氮罐中,分别于冻存1周及4个月后复苏并构建类器官。结果: 12份新鲜肺癌组织均成功构建类器官;冻存1周及4个月的样本复苏后分别有9例和6例成功构建类器官,成功率分别为75.0%(9/12)和50.0%(6/12),类器官形态及肿瘤标志物表达与新鲜样本来源的类器官基本一致;冻存4个月的样本复苏后,细胞活性低于55%的样本均未能成功构建类器官。结论: 小样本探索性研究提示,尽管长期玻璃化冻存对细胞活性存在一定影响,但经其处理的肺癌手术标本可基本满足类器官的构建需求。

Abstract:

Objective: To explore the feasibility of employing vitrification cryopreservation, an advanced cryopreservation technique, for preserving surgically resected lung cancer tissues to facilitate subsequent organoid generation. Methods: We prospectively collected tumor specimens from 12 patients with histologically confirmed lung cancer at Beijing Chest Hospital, Capital Medical University from July to August 2024. Following standardized pathological procedures, the tissues were immediately immersed in preservation medium, maintained at 4 ℃ during transportation, and processed within 2 hours. Each specimen was systematically divided into three aliquots of approximately 0.5 cm3. One was processed fresh for organoid culture (serving as the control), while the remaining two were subjected to vitrification cryopreservation and stored in a vapor-phase liquid nitrogen tank. The cryopreserved samples were subsequently thawed at two time points (1 week and 4 months) for comparative assessment of organoid culture. Results: All fresh specimens (100.0%, 12/12) successfully generated organoids. Vitrified samples showed success rates of 75.0% (9/12) and 50.0% (6/12) at 1-week and 4-month time points, respectively. Crucially, cryopreserved-derived organoids maintained morphological characteristics and tumor marker expression profiles comparable to those of the fresh controls. Notably, all specimens with post-thaw viability <55% after 4 months of storage failed to organoid generation. Conclusion: This small-scale study indicates that although long-term vitrification cryopreservation exerts certain detrimental effects on cell viability, the processed surgical specimens can still meet the requirements for organoid construction.
