Three-dimensional porous scaffolds play a critical role in both ________ and _________ strategies?

The involvement of three-dimensional porous scaffolds in tissue engineering is fundamentally linked to their ability to support cellular processes that are crucial for tissue regeneration and repair. Scaffolds are designed to mimic the natural extracellular matrix (ECM), providing a supportive structure for cells to adhere, proliferate, and differentiate.

In terms of cell targeting, scaffolds can be engineered to present specific biochemical cues that attract desired cell types to the site of tissue regeneration. This is essential for ensuring that the right cells are present to facilitate the healing process and restore functionality to damaged tissues.

On the other hand, cell transplantation refers to the technique of introducing cells into the body, often in conjunction with the scaffold, to enhance tissue repair. The porous nature of the scaffold allows for the adequate distribution of cells throughout the three-dimensional space, improving their integration and function within the host tissue.

Therefore, three-dimensional porous scaffolds play a pivotal role in both the targeting of specific cell types to the appropriate tissue area and in the successful transplantation of those cells to promote effective tissue regeneration. This contributes to the overall effectiveness of tissue engineering strategies designed to repair or replace damaged tissues or organs.
