Summarised results of vascular endothelial growth factor (VEGF) immunostaining

Percentage of VEGF positive chondrocytes
Normal cartilage samples (n=6)56 (13.0)
Mild OA samples (n=8)51.4 (11.2)
Moderate OA samples (n=9)53.2 (12.8)
Severe OA samples (n=10)82.21-150(6.9)
  • Percentages of VEGF positive chondrocytes throughout the entire depth of the specimens. In each specimen 100 chondrocytes were counted twice using a high power magnification field. Percentage of VEGF immunostained chondrocytes are given as means (SD).

  • 1-150 p<0.05 (versus percentage of positive chondrocytes in normal cartilage).
