Flashcards

Tissue Engineering

The creation of functional tissues or organs that can restore, maintain, or enhance damaged tissues.

Regenerative Medicine

A field of research focused on stimulating the body's natural healing powers to repair or replace damaged tissues or organs.

Engineered Tissues

Artificial tissues designed to mimic natural tissues, such as skin or cartilage.

FDA-Approved Engineered Tissues

The FDA has approved the use of certain artificial tissues, such as skin and cartilage, for medical purposes.
