PDX和PDO我知道了,什么是PDXO? - 知乎专栏
PDX-derived organoids (PDXOs) 是用前期已经传代到小鼠模型用于扩增的患者肿瘤组织制作的三维体外模型,更简单地说,PDXO是来自于体内PDX的体外模型。 PDXOs are generated using the same protocols as patient-derived organoids (PDO, developed directly from patient tumor tissue). For both models, cancer stem cells (CSCs) are preserved and give rise to cancers found in human patients.
PDO类器官—用于药物筛选_模型 - 搜狐
2021年3月8日 · PDO直接来源于患者肿瘤组织,包含原发肿瘤的肿瘤干细胞(CSC),CSC能够自我更新并分化,所以PDO再现了原发肿瘤内的细胞多样性,且能够真实反应其亲代肿瘤的基因组、形态和病理生理学特征。 例如,已证明胰腺肿瘤类器官可保持致癌基因突变,如KRAS、TP53、SMAD、CDKN2A及扩增的MYC等,以及肿瘤抑制基因TGFBR2和DCC的缺失。 | 基于PDO的技术 …
Patient-derived organoids (PDOs) and PDO-derived
2022年12月1日 · Patient-derived models of cancer (PDMC), such as patient-derived xenografts (PDXs) and patient-derived organoids (PDOs), have been developed aiming to address the limitations of the conventional models. Both PDO and PDX capture the clinical heterogeneity of cancer in terms of stage, molecular features, and genetic background.

2021年3月4日 · 类器官是一个三维“微器官模型”,它是通过Self-organization的不同类型的干细胞而制备的,可以模拟天然器官的结构和功能。 与传统的二维培养模型相比,类器官可以代表整个生物体的生理过程,具有更接近体内细胞组成和行为,基因组更稳定,更适合生物转染和高通量筛选的优点。 与动物模型相比, 类器官模型 的操作不仅更简单,而且还可以用于研究疾病发生和发展的机制。 | 类器官Organoid/Patient Derived Organoid,PDO 目前研究人员倾向于使用体外模型进 …
Modeling lung adenocarcinoma metastases using patient-derived …
2024年10月15日 · Using well-characterized lung adenocarcinoma (LUAD) patient-derived organoids (PDOs), we establish an in vivo metastasis model that preserves the biologic features of human metastases.
Patient-derived organoids and mini-PDX for predicting
2024年9月30日 · Using these PDO lines and a PDO-derived mini-PDX model, we found that the combination of afatinib and gemcitabine induced synthetic lethality in MET N375S mutant lung cancer. Our study demonstrates that PDOs combined with targeted genomic sequencing can assist providers in making clinical decision.
