From: Identification of sensory fiber types in mouse temporomandibular joint tissues
Peptidergic myelinated and non-myelinated fibers in the joint capsule, anterior disc and retrodiscal tissues. (A) The left column shows NFH-positive fibers (A-fibers), the middle column shows CGRP-positive (peptidergic fibers) fibers in CGRP/tdTom mouse and the right column shows co-expressions of CGRP and NFH-positive fibers in the mouse joint capsule, anterior disc and retrodiscal tissues. Pictures from the joint capsule, anterior disc and retrodiscal tissues as well as antibodies used and corresponding colors are indicated. Yellow arrows mark CGRP+/NFH+ fibers, blue arrows show CGRP+/NFH- nerves and white arrows mark seldomly encountered CGRP-/NFH+ nerves in the anterior disc. (B) Relative percentages for CGRP+/NFH-, CGRP+/NFH- and CGRP-/NFH+ nerves in the joint capsule, anterior disc and retrodiscal tissues. Statistics is 2-way ANOVA Bonferroni’s pot-hoc test (n = 5).
