Figure 1From: Induction of nerve growth factor expression and release by mechanical and inflammatory stimuli in chondrocytes: possible involvement in osteoarthritis painStimulation of NGF release by cartilage compression. Explants of costal cartilages from Swiss mice were compressed (C) or not (NC) for 4 and 24 hours (n = 4). NGF protein levels were measured in conditioned media. *P <0.05.
