In tissue engineering, what is the main purpose of a scaffold?

The primary role of a scaffold in tissue engineering is to support cell attachment and growth. Scaffolds are designed to serve as a three-dimensional framework that mimics the natural extracellular matrix, providing an environment for cells to anchor, proliferate, and differentiate. They facilitate the organization of cells in a manner that resembles native tissue, which is critical for developing functional tissues.

The properties of the scaffold, such as its porosity and surface characteristics, play a significant role in promoting cellular activities. Cells need surfaces to attach to, and without an appropriate scaffold, they may not behave as needed for productive tissue formation. This interconnected structure allows for nutrient diffusion and waste removal, further supporting cell viability and function.

While scaffolds can contribute to the mechanical properties of the tissue, their primary function centers around creating a conducive environment for cells, thus emphasizing the importance of cell attachment and growth in the tissue engineering process.
