CELL CULTURE SUBSTRATE FOR RAPID RELEASE AND RE-PLATING

摘要

The invention pertains to devices and methods for rapid release of a patterned tissue module. The invention pertains to a device comprising a substrate and a pattern of shape- memory polymer fabricated upon the substrate, wherein the shape-memory polymer is converted to a deformed state by exposure to an external stimulus, for example, a change in temperature, pH, ionic strength, solvent, salt, surfactant, or an electric or magnetic field. The invention also pertains to a method of releasing a patterned tissue module, the method comprising the steps of plating cells in the device of the invention, culturing the cells to produce the patterned tissue module on the pattern of shape-memory polymer, applying the external stimulus to the device, and collecting the patterned tissue module released from the pattern of shape-memory polymer.
