  3. To develop new drugs and therapies

  4. To repair damaged tissues and organs


Correct Option: D
Explanation:

Tissue engineering aims to use cells, scaffolds, and growth factors to create functional tissues and organs that can be used to repair or replace damaged tissues and organs in the body.

Which of the following is NOT a key component of tissue engineering?

  1. Cells

  2. Scaffolds

  3. Growth factors

  4. Biomaterials


Correct Option: D
Explanation:

Biomaterials are not a key component of tissue engineering. Cells, scaffolds, and growth factors are the three main components.

What is the role of cells in tissue engineering?

Correct Option: D
Explanation:

Cells play a vital role in tissue engineering by providing the building blocks for new tissue, secreting growth factors and other signaling molecules, and helping to organize and structure the new tissue.

What is the role of scaffolds in tissue engineering?

  1. To provide a temporary framework for cell growth

  2. To deliver growth factors and other signaling molecules

  3. To help organize and structure the new tissue

  4. All of the above


Correct Option: D
Explanation:

Scaffolds play a vital role in tissue engineering by providing a temporary framework for cell growth, delivering growth factors and other signaling molecules, and helping to organize and structure the new tissue.

What is the role of growth factors in tissue engineering?
