SPRY4 Acts as an Indicator of Osteoarthritis Severity and Regulates Chondrocyte Hypertrophy and ECM Protease Expression

Using SPRY4 gene delivery into healthy and degenerated chondrocytes, investigators elucidated the role of SPRY4 in preventing chondrocyte hypertrophy. In addition to using the human cartilage tissues with the destabilization of the model in Sprague-Dawley rats, the role of SPRY4 in cartilage tissues and chondrocytes was explored through their molecular and histological analysis.
