Functional peptides for cartilage repair and regeneration.

Cartilage repair after degeneration or trauma continues to be a challenge both in the clinic and for scientific research due to the limited regenerative capacity of this tissue. Cartilage tissue engineering, involving a combination of cells, scaffolds, and growth factors, is increasingly used in cartilage regeneration. Due to their ease of synthesis, robustness, tunable size, availability of functional groups, and activity, peptides have emerged as the molecules with the most potential in drug development.
