What kind of scientists are involved with Magnetic Resonance Imaging?

• Electrical Engineers: electromagnetics
• Computer Engineers/Scientists: computation
• Physiologists: biological function
• Chemists: new imaging agents
• Psychologists: mental function
• Physicians: medical implications

Cell and Tissue Engineering

• Cell and Tissue Engineering allows us to repair or replace the function of natural tissue with bioengineered substitutes.
• Principles of engineering, chemistry, and biology are combined to create tissue substitutes from living cells and synthetic materials.

• Tissue Engineered Skin

• New Companies: Advanced Tissue Sciences, Inc.
• Organogenesis

The Potential Promise of Tissue Engineering

• To repair or replace damaged organs
• Origins in the late 1980s
• Rapid advances in stem cell biology
• The tissue engineer needs to
• manipulate,
• produce, and
• deliver
• collections of cells as building blocks of tissues
