The aims are: (1) to characterize the role of lipids in signal transduction by ECM molecules for tumor cell pseudopod protrusion and migration; (2) to determine the response of intracellular calcium cations in tumor cells to lipid-mediated ECM molecule stimulation; (3) to examine the response of the cytoskeletal actin network upon lipid- mediated ECM molecule stimulation during the two phase pseudopod protrusion; and (4) to construct a two phase pseudopod model integrating engineering sciences with cell biology and derive mechanistic parameters that may affect tumor cell migration.

其目的是：(1)表征脂质在信号中的作用 ECM分子转导肿瘤细胞伪足突起和 迁移；(2)测定细胞内钙离子的反应 肿瘤细胞内阳离子对脂质介导的细胞外基质分子刺激的影响 为了研究细胞骨架肌动蛋白网络对脂质的反应- 两相伪足过程中介导的ECM分子刺激 (4)构建两相伪足模型 以细胞生物学为基础的工程科学，并得出机械参数 这可能会影响肿瘤细胞的迁移。
