Fig. 2From: Articular cartilage gene expression patterns in the tissue surrounding the impact site following applications of shear and axial loadsSpecimen locations. Full-thickness cartilage specimens were harvested from the location directly below the impact site (AOI sample in blue), and in the tissue adjacent to the impaction site (ADJ sample in yellow). The relative size of the axial specimens is shown on the left, and the shear on the right. This figure is for demonstration only, actual patellae were given identical treatments on each facetBack to article page
