In regenerative medicine, collagen and biodegradable polymers are essential for creating tissue scaffolds, which serve as the structural foundation for growing bioartificial tissues.12

The Role of Collagen

Collagen is a natural protein that provides structural integrity, elasticity, and tensile strength to tissues. Because it is a major component of the extracellular matrix in the body, it is highly effective as a biomimetic scaffold. It supports cell attachment and proliferation, helping to maintain the necessary environment for cells to organize into functional tissues.341

The Role of Biodegradable Polymers

Biodegradable polymers are used to create synthetic scaffolds that provide temporary mechanical support while new tissue forms. Their primary advantage is that they are designed to be absorbed or dissolved by the body over time, eliminating the need for surgical removal. By adjusting the chemical structure of these polymers, scientists can control the rate of degradation to match the speed at which the patient's own cells regenerate the damaged tissue.52
