Fig. 6From: The role of intra-articular neuronal CCR2 receptors in knee joint pain associated with experimental osteoarthritis in miceRepresentative confocal images of the right knee of a 10-week-old male naïve Ccr2RFP mouse, immunostained with CGRP. a CGRP/CCR2 overlay of the lateral compartment of the knee; b magnified white inset of a showing CCR2, CGRP signals and the overlay of both images. White arrows indicate an example of an overlap between CGRP and CCR2 signals (CCR2 receptors present on CGRP+ nerve fiber). c CGRP/CCR2 overlay of the medial compartment of the knee, an area where we do not see a high amount of innervation in naïve mice. Scale bar for a, c = 100 μm. Scale bar for b = 25 μmBack to article page
