细胞侵袭指细胞穿越组织或细胞间的基底膜和间质，参与生理过程如细胞迁移、组织发育及肿瘤转移。该过程涉及蛋白酶解、胞外基质附着和细胞运动等。细胞侵袭的研究常借助Transwell实验、Boyden室和基底膜模型等技术，以评估细胞侵袭能力，并有助于揭示疾病发展及治疗策略。

Cell invasion refers to cells crossing the basement membrane and stroma between tissues or cells and participating in physiological processes such as cell migration, tissue development and tumor metastasis. This process involves proteolysis, extracellular matrix attachment, and cell movement. Research on cell invasion often uses techniques such as Transwell assay, Boyden chamber and basement membrane model to evaluate cell invasion ability and help reveal disease development and treatment strategies.
