Tissue Engineering By Tyler Gagan BME 281 Section 2
Overview • Isolation of patients cell • Creation of synthetic scaffold • Proliferation of cells onto scaffold
History • 1970’s: (John F. Burke) First skin substitute. Purified shark collagen, long sugar molecule. • 1970’s-1980’s First successful human derived skin substitute procedure (Howard Green, Harvard Medical)
Modern Application • Repair of damaged cells • Replacing non-existent cells • Artificial organ parts/entire organs
Limitations • Very long cell adhesion time. • Thick tissues need vascularization. • Proper cell environment is tough to mimic.
Future • Increased growth rate and adhesion rate • Growth of entirely biocompatible organs. • Stocked tissue databases.
