A scaffold is a temporary structure used in tissue engineering and regenerative medicine to support the growth of cells and promote tissue formation. Scaffolds are often made from biocompatible materials such as polymers, ceramics, or natural substances, and are designed to mimic the extracellular matrix of the tissue being regenerated. Scaffolds provide a framework for cells to attach to, proliferate, and differentiate, ultimately leading to the formation of functional tissue. Research in scaffold design focuses on creating structures with the appropriate mechanical properties, porosity, and surface chemistry to effectively support cell growth and tissue regeneration. Scaffolds play a crucial role in a variety of applications, including wound healing, bone regeneration, and organ transplantation.
