Cytokine expression of articular chondrocytes

Cytokine	Mouse strain	Sex	Age (months)	% Positive chondrocytes (medians)
Cytokine	Mouse strain	Sex	Age (months)	Medial	Lateral
The total numbers of articular chondrocytes in each thin section were determined for the medial and the lateral sides of the joints and the percentages of positively stained chondrocytes and corresponding medians were calculated.
