C. Synthesis of biologically active scaffolds (regeneration templates) 1. History of biologically active scaffolds (regeneration templates). 2. Physical chemistry of collagen: Melting of collagen quaternary structure (thromboresistance). Melting of collagen tertiary structure (gelatinization). 3. Synthesis of ECM analogs: lonic complexation

TISSUE ENGINEERING What is tissue engineering Production of tissue in vitro by growing cells in porous, absorbable scaffolds (matrices). Why is tissue engineering necessary? Most tissues cannot regenerate when injured or diseased

UNIT CELL PROCESSES Concept of a \Control Volume\ around a Cell Soluble Regulator Cell Matrix

C. Cell-Matrix Interactions A. How cells pull onto and deform the matrix to which they attach themselves. B. Cell-matrix interactions control the spontaneous closure of wounds in organs. C. What happens when regeneration is induced?
