Biofabrication

Definition

Biofabrication is the process of creating biological structures using living cells, biomaterials, and advanced manufacturing techniques. This approach blends biology, engineering, and materials science to produce complex tissue-like constructs that can potentially replace or repair damaged biological tissues and organs. Biofabrication plays a crucial role in regenerative medicine and is often executed through methods like 3D bioprinting, which allows for precise control over the spatial arrangement of cells and materials.
