Muscle tissue scaffolding

Definition

Muscle tissue scaffolding refers to a three-dimensional framework designed to support the growth and regeneration of muscle cells. This scaffold provides a suitable environment for muscle cells to adhere, proliferate, and differentiate, mimicking the natural extracellular matrix found in skeletal muscle. The design of these scaffolds is critical in developing effective therapies for muscle injuries or degenerative diseases.
