Fig. 4.

Relative gene expression of pro- and anti-inflammatory factors and nerve markers in bursae of healthy group 1 (n = 5), group 2 with osteochondral pathology without RC tear (n = 5), group 3 with partial SSP tear (n = 6) and group 4 with full-thickness SSP tear (n = 16). qRT-PCR data were normalized to the expression of the house keeping gene 18S rRNA. The data are shown as fold values to the healthy group (dashed line) and given as individual dot plots with median and interquartile range. For MMP1 no expression was detected in the healthy group 1 and values were set to a fold of 1. Statistics: Dunn’s Multiple Comparison Test
