Figure 4.

Immunogold localization of elastin in the distal region of the periodontal ligament of the distal root. (A) Five-nm gold particles are scattered within assemblies of microfibrils (MF) localized very close to a fibroblast (FB) in the vicinity of blood vessels. (B) Longitudinal section of assemblies of microfibrils onto which clusters of gold particles are localized. (C) Clusters of gold particles are more clearly seen within assemblies of oblique-transversely sectioned microfibrils. Bars: A,C = 200 nm; B = 100 nm.
