Abstract
The present invention relates to the arrangement of one or more cells in a medium or on a substrate through the use of boundary conditions, which are changes in local environment compared to the medium or substrate alone or cause an alteration of cell response upon interaction of a cell with the boundary condition.
Claims10
An in vitro method of forming a mature muscle tissue, comprising:
- (a) providing a medium or substrate;
- (b) providing a boundary condition associated with the medium or substrate, wherein said boundary condition directs the alignment and development of dissociated muscle cells to form a mature muscle tissue;
- (c) providing the dissociated muscle cells to the medium or substrate, wherein the muscle cells arrange based upon the boundary condition;
- and
- (d) culturing the muscle cells to form a mature muscle tissue,
- wherein the boundary condition directs the movement and growth of the muscle cells upon interaction with the boundary condition as compared to interaction with the medium or substrate alone such that substantially all of the muscle cells and sarcomeres within the muscle cells are spatially anisotropic in at least one direction and substantially all of the muscle cells coordinately contract, thereby forming a mature muscle tissue.
