Temporally increased 4-sulfated chondroitin sulfate promotes proper progression of bone morphogenetic protein 4-mediated chondrogenic differentiation.

Chondroitin sulfate (CS) is a principal extracellular matrix component in cartilaginous tissues, well known for its role in cartilage elasticity owing to its physicochemical properties. However, its intrinsic role in chondrogenesis remains unelucidat…
