研究概要

该方案保证了灵活性和可靠性,同时为质量控制检查提供了有用的指南,以支持不同的实验设置。建立稳健的肺癌 PDO 培养建立和扩增方案,是其应用于癌症研究以及作为临床实践中的预测工具的关键要求。

研究思路结论见上方概要

尽管引入了创新疗法,肺癌仍然是癌症相关死亡的主要原因。因此,肺癌仍需要深入表征,以识别可用于开发新型治疗策略的细胞和分子靶点。三维细胞模型,包括患者来源类器官(PDOs),是研究肺癌生物学的有用工具,未来可能作为治疗决策中的预测工具。然而,由于成功率低和/或正常气道上皮细胞过度生长,成功建立忠实代表相应患者组织的肺癌类器官培养仍然具有挑战性。

我们建立了一个两步方案,可用于建立短期和长期3D培养,二者具有不同的特性和成功率。

肿瘤组织来源球体(CTOSs)显示出100%的成功率,并允许同时分离自体肿瘤浸润白细胞(TILs)。相反,PDOs可以中长期扩增并生物库保存,但成功率较低,且可能被正常气道上皮细胞污染。为克服这些问题,我们建立了最佳培养基配方并实施了严格的质量控制,从而显著提高了肿瘤性PDO建立的成功率。

We set up a two-step protocol that allows for establishing both short-term and long-term 3D cultures, with different characteristics and success rates.

Cancer tissue-originated spheroids (CTOSs) show a 100% success rate and allow for the concomitant isolation of autologous tumor infiltrating leukocytes (TILs). On the contrary, PDOs can be expanded for a medium-long term and bio-banked but retain a lower success rate and the possibility of contamination with normal airway epithelial cells. To overcome these problems, we set up an optimal medium formulation and we implemented rigorous quality controls, leading to a substantial improvement in the success rate of tumoral PDO establishment.

Overall, this protocol guarantees flexibility and reliability, also providing useful guidelines for quality control checks to support different experimental settings. The setting up of a robust protocol for lung cancer PDO culture establishment and expansion is a key requirement for their employment both in cancer research and as predictive tools in clinical practice.
