Cell Adhesion


Project Description

Cell-cell and cell-substrate adhesion can influence several biologically important processes such as tissue homeostasis, wound healing and even cancer metastasis. With the advancement of nano and microtechnological tools, we can now quantitatively probe cell-cell adhesion forces not only at the cellular but also molecular level. Here, we investigate the structure and function of cell adhesion proteins, quantify the adhesion forces between these proteins and examine their association with certain diseases.
