Elaunin (Greek verb ἐλαύνω "I steer") is a component of elastic fibers formed from deposition of elastin between oxytalan fibers. It is found in the periodontal ligament and the connective tissue of the dermis, particularly in association with sweat glands.[1]
Unlike Oxytalan fibres, elaunin fibres stain with orcein, aldehyde fuchsin and resorcin fuchsin without prior oxidation.
Elaunin fibers have been found within the secretory coil of human eccrine sweat glands. They were found in bundles of microtubules which had a different constancy than elastic fibers. The elaunin fibers found in the secretory coil had a less thick appearance than that of elastic fibers.[2]
Elaunin can be identified where the fibers of the gingival ligament are.
There are elastic fibers, and one of the main types of elastic fibers is elaunin.
In the papillary dermis, elaunin is lost when in reduction.
