1. What is the purpose of introducing scaffolds in TE?
The purpose of introducing scaffolds in tissue engineering is to provide a structure that aids in cell growth and tissue formation. Scaffolds act as a basic support for cell development and play a crucial role in tissue regeneration. They provide a framework that helps cells adhere, migrate, proliferate, and differentiate to create functional tissues. Scaffold properties such as biocompatibility, biodegradability, mechanical strength, pore size, and cell interaction are essential in determining their effectiveness in tissue engineering applications.
2. What are the main properties of scaffolds?
Main Properties of Scaffolds:
The main properties of scaffolds include:
- Biocompatibility
- Biodegradability
