Abstract

To discover new treatment options for high-grade glioma (HGG), robust in vitro models are essential, but reliably establishing patient-derived cell cultures remains challenging. We established glioma stem-like cell (GSC) cultures from 114 consecutive HGG specimens via traditional surgical resection and/or ultrasonic aspiration, using completely dissociated single cell (single cell-derived, SCD) and partially dissociated 3D-derived (3DD) tissue fragments. Higher success rates in culture establishment were obtained from ultrasonic aspirates and 3DD surgical samples. Combining these approaches yielded a 96% success rate. Copy number profiling showed overall genetic similarities between cultures and parental tissue. Single-cell sequencing revealed greater transcriptomic heterogeneity in ultrasonic aspiration-derived cultures. Our protocol enabled the screening of 20 anti-cancer agents within a clinically relevant timeframe for 16 out of 18 HGG samples. This refined protocol serves as a robust tool for establishing HGG cell cultures that retain the molecular characteristics of the tumors and support applications in precision medicine.

摘要

为了发现高级别胶质瘤（HGG）的新治疗方案，强大的体外模型至关重要，但可靠地建立患者来源的细胞培养物仍然具有挑战性。我们通过传统手术切除和/或超声抽吸，使用完全解离的单细胞（单细胞衍生，SCD）和部分解离的3D衍生（3DD）组织片段，从114例连续的HGG标本中建立了胶质瘤干细胞样细胞（GSC）培养物。从超声抽吸物和3DD手术样本中获得了更高的培养成功率。结合这些方法成功率达到了96%。拷贝数分析显示培养物与亲本组织之间总体遗传相似性。单细胞测序揭示了超声抽吸来源的培养物中更大的转录组异质性。我们的方案能够在临床相关时间范围内对18个HGG样本中的16个进行20种抗癌药物的筛选。这种优化的方案是建立保留肿瘤分子特征并支持精准医学应用的HGG细胞培养物的强大工具。
