Abstract
The present invention is related to a method for the production of cell sheets comprising at least two different cell types, said method comprising the steps of providing a continuous cell sheet which is disposed on a substrate comprising shape transition properties and/or alterable surface characteristics; exposing said continuous cell sheet to a releasing agent in a patterned fashion; washing the cell sheet after exposure to the releasing agent in order to remove cells which have been affected by the releasing agent, and repopulating the gaps remaining after the cells which have been affected by the releasing agent have been removed with a second cell type.
