Study Notes

Tissue Engineering and Regenerative Medicine

  • The goal of tissue engineering is to create functional tissue substitutes that can replace or repair damaged or diseased tissues and organs.

Examples of Engineered Tissues

  • One example of an engineered tissue approved by the FDA is a skin substitute.

Regenerative Medicine

  • Regenerative medicine encompasses tissue engineering, as well as self-healing and the stimulation of the body's own repair mechanisms.

Relationships between Terms

  • Tissue engineering is a subset of regenerative medicine.
  • The terms 'tissue engineering' and 'regenerative medicine' are related and often used interchangeably.

Key Components of Tissue Engineering

  • The key components combined in tissue engineering are biomaterials, cells, and biochemical factors.

Focus of Tissue Engineering

  • The primary focus of tissue engineering is to develop functional substitutes for damaged tissues and organs.

Distinguishing Regenerative Medicine

  • Regenerative medicine distinguishes itself from tissue engineering by focusing on the stimulation of the body's own repair mechanisms, in addition to tissue engineering.

Artificial Skin and Cartilage

  • Artificial skin and cartilage are mentioned in the context of tissue engineering as examples of engineered tissues that can replace or repair damaged tissues.

Interchangeable Terms

  • The terms 'tissue engineering' and 'regenerative medicine' have become largely interchangeable due to their overlap in goals and approaches.

Goal of Regenerative Medicine

  • The ultimate goal of regenerative medicine is to restore or establish normal function in damaged or diseased tissues and organs.
