简化了为患者衍生异种移植 (PDXs) 创造一个人性化的利基. 可注射生物材料和静脉输送为PDX模型中的急性髓性白血病 (AML) 植入提供了强大的,方便的方法.
科学领域:
- 生物医学工程 生物医学工程
- 在瘤学瘤学.
- 翻译研究是翻译研究.
背景情况:
- 患者衍生异种移植 (PDX) 是癌症研究中宝贵的工具.
- 人性化的利基增强了PDX模型的忠实性,但目前的方法很复杂.
- 简化PDX人性化对于更广泛的采用至关重要.
研究的目的:
- 确定为急性髓性白血病 (AML) 移植创造人性化支架的基本步骤.
- 为了简化人性化的利基创建和AML异种移植的协议.
- 建立一个方便和强大的方法来生成AML PDX模型与人性化的利基.
主要方法:
- 七种不同的生物材料用于脚手架的比较.
- 评估细胞外矩阵凝和定制的原纤维,以形成利基.
- 通过不同的途径植入后AML细胞透的评估 (静脉注射与内部支架).
主要成果:
- 细胞外基质凝和定制的原纤维提供了最高水平的骨髓利基.
- 这两种生物材料都允许简单的非手术植入.
- 生物材料的选择没有影响随后的AML透.
- 标准静脉注射产生了最强大的AML移植,即使在具有挑战性的样本中.
- 与静脉注射相比,内输送没有任何优势.
结论:
- 一种可注射生物材料用于架构创建,与静脉注射AML异种移植相结合,是最方便和最强大的方法.
- 这种简化方法使AML PDX模型与人性化的利基的生产更容易.
- 这些发现为在AML研究中更广泛地使用人性化的PDX模型铺平了道路.
