FIG. 3.

Shows tenocyte markers expressed predominantly in the tibial insertion site. A–D show tenascin-C, F–J show biglycan, and K–N show COMP staining using specific antibodies. In each panel, red is specific stain, and blue shows cell nuclei stained using DAPI. Scale bar=100 μm. E and J show semi-quantitation of the antibody staining by measurement of pixel intensity. Scale bar=100 μm. Error bar represents standard error, and the asterisk represents statistical significance (p<0.05). COMP, cartilage oligomeric protein.
