title: Precise manipulation of cell behaviors on surfaces for construction of tissue/organs.
abstract: The use of micro/nanotechnology has become an indispensable strategy to manipulating cell microenvironments. By employing key elements of soft lithographical technologies including self-assembled monolayers (SAMs), microcontact printing (μCP), and microfluidic pattering (μFP) and a number of switchable surfaces such as electrochemical active, photosensitive, and thermosensitive surfaces, scientists can control the adhesion, proliferation, migration and differentiation of cells. By combining essential in vivo conditions, various physical or pathological processes such as cell-cell interaction in wound healing and tumor metastasis could be studied on well-defined surfaces and interfaces. By integrating key elements in live tissues, in vitro models mimicking basic structure and function of vital organs such as lung, heart, blood vessel, liver, kidney, and brain have been developed and greatly increased our knowledge of these important life processes. In this review, we will focus on the recent development of these interfacial methods and their application in fundamental biology research.
