Tissue scaffolds are three-dimensional structures designed to support the growth of new tissues in the body. They provide a framework for cells to attach, proliferate, and differentiate, mimicking the natural extracellular matrix found in tissues. These scaffolds can be made from various materials, including biodegradable polymers, natural proteins, or ceramics, and are often used in regenerative medicine. In tissue engineering, scaffolds play a crucial role in repairing or replacing damaged tissues and organs. They can be engineered to have specific properties, such as porosity and mechanical strength, to match the requirements of the target tissue. Researchers are exploring ways to enhance scaffold functionality through techniques like 3D printing and incorporating growth factors to promote healing.
