Figure 8From: Expression of matrix metalloproteinase-1 (MMP-1) in Wistar rat's intervertebral disc after experimentally induced scoliotic deformity Increased number of chondrocyte-like disc cells at A) the transition zone and B) the margin of the intervertebral disc adjacent to the vertebral end plates. Note the difference between the normal chondrocytes (red arrows) and other chondrocyte-like cells, which were immunopositive for MMP-1 (yellow arrows).Back to article page
