1122-PDX模型在肿瘤治疗中的技术与应用研究

from 聊聊Sci

该系列文章主要探讨了人源肿瘤异种移植(PDX)模型在癌症研究中的核心地位。PDX模型通过将患者肿瘤组织植入免疫缺陷小鼠,能够高度精准地模拟人类癌症的病理特征、基因图谱和肿瘤内部的异质性。相较于传统细胞系,它在新药临床前评价、个体化精准医疗、耐药机制探索以及生物标志物开发方面展现出无可比拟的优势。文章详尽介绍了PDX从模型构建、技术演进到多组学集成的全过程,并分析了其在化疗、靶向治疗及免疫治疗领域的广泛应用。尽管面临基质置换和维持成本高等挑战,PDX依然是当前连接基础研究与临床转化最为可靠的“替身”模型。References:Liu Y, Wu W, Cai C, Zhang H, Shen H, Han Y.
