肿瘤血管生成是肿瘤生长和转移的基础,针对这一过程已开发出抗血管生成的治疗方法。然而,这些治疗的临床成功是有限的,这可能部分是由于对细胞-微环境相互作用及其在肿瘤血管生成中的作用的不完全了解。传统上,二维(2D)培养方法被用于研究肿瘤的体外进展,但这些系统无法真实地再现有助于体内肿瘤血管生成的肿瘤微环境条件。通过将癌症生物学与组织工程和药物输送方法相结合,生物启发的肿瘤模型的开发应运而生。这样的3D模型系统可以研究可溶性因子信号、细胞-细胞外基质(ECM)相互作用、细胞-细胞相互作用、机械信号和代谢应激的特定作用。本章讨论了组织工程肿瘤模型的特定生物和工程设计考虑因素,并强调了它们在确定肿瘤血管生成基础方面的应用。
Tumor angiogenesis is fundamental to tumor growth and metastasis, and antiangiogenic therapies have been developed to target this process. However, the clinical success of these treatments has been limited, which may be due, in part, to an incomplete understanding of cell–microenvironment interactions and their role in tumor angiogenesis. Traditionally, two-dimensional (2D) culture approaches have been used to study tumor progression in vitro, but these systems fail to faithfully recreate tumor microenvironmental conditions contributing to tumor angiogenesis in vivo. By integrating cancer biology with tissue engineering and drug delivery approaches, the development of biologically inspired tumor models has emerged. Such 3D model systems allow studying the specific role of soluble factor signaling, cell–extracellular matrix (ECM) interactions, cell–cell interactions, mechanical cues, and metabolic stress. This chapter discusses specific biological and engineering design considerations for tissue-engineered tumor models and highlights their application for defining the underpinnings of tumor angiogenesis.
