まとめ
先进的肝细胞癌(HCC)患者来源的芯片模型显示,标准疗法并未影响肿瘤细胞,这凸显了新药发现方法的必要性。这些模型有效地评估了肿瘤微环境中药物的反应。
科学分野:
- 肿瘤学
- 生物技术
- 药物发现
背景:
- 肝细胞癌(HCC)是一种普遍的肝脏癌症,发病率不断上升,与晚期肝病有关。
- 包括细胞基质和血管系统在内的肿瘤微环境,对HCC的进展和治疗反应至关重要。
- 开发先进模型对于HCC的早期药物和靶点发现至关重要。
研究 の 目的:
- 使用血管化的肝细胞癌患者来源芯片(PDChip)模型进行表型筛选。
- 评估28种治疗条件对PDChip模型中的原发性HCC肿瘤和细胞系的效果。
- 评估药物对肿瘤细胞存活率、肿瘤相关血管系统以及趋化因子/细胞因子谱的影响。
主な方法:
- 使用了大约1200个源自8个原发性HCC肿瘤和2个细胞系的HCC PDChip。
- 在灌注流下培养PDChip,并将其暴露于各种治疗条件下。
- 评估了细胞存活率、血管床组织结构以及趋化因子和细胞因子释放变化的结局。
主要な成果:
- 标准疗法(索拉非尼、仑伐替尼)降低了PDChip模型的存活率,但未影响HCC肿瘤细胞。
- 阿托伐他汀降低了PDChip的存活率,但未改变血管床的组织结构。
- 几种测试药物调节了趋化因子和细胞因子的释放,其中对IL6水平有显著影响。
結論:
- HCC PDChip模型为评估肿瘤及其微环境中的药物反应提供了一个强大的平台。
- 这些模型对于临床前研究很有价值,有助于疾病的理解和新型HCC治疗方法的开发。
- 该研究强调了当前疗法的局限性以及新候选药物在调节HCC微环境方面的潜力。

The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
