The present invention provides methods for manipulating the intrinsic strain of cells by treating tissue engineered constructs or native tissue with compounds which affect the intrinsic strain setpoint of the cells in order to modulate matrix synthesis, secretion, organization and/or remodeling so that the tissues withstand in vivo mechanical forces and have the structural characteristics of host tissue which has been permanently altered by injury, atrophy or disease. The compounds include binding site peptides, ATP, UTP and related analogues, IL-1β, TGF-α, cytochalasin D, hyaluronic acid, nocodazole and others. Also provided are methods for applying a mechanical external strain to the tissues, as well as methods for modulating the expression of cytoskeletal genes that transcribe cytoskeletal proteins which regulate a cell's intrinsic strain setpoint.
A method for manipulating intrinsic strain of cells, comprising treating the cells either in vivo or in vitro with a compound that affects intrinsic strain setpoint of the cells in order to modulate cell-cell connections, cell-matrix connections, extracellular matrix synthesis, secretion, stiffness, organization and/or remodeling, material properties, or attachment of the cells to the matrix via integrins or other integrin-like cell-matrix attachments.
