Abstract
This freeze fracture study shows the presence of focal tight junctions (maculae occludentes) between the mesenchymal cells in the connective tissue matrix of embryonic and fetal dermis. The overall outline of these unique junctions varies from circular to very angular. The junctional elements are most frequently present in a groove on the E fracture face. The corresponding P fracture face has ridges delineating the junction. These intercellular junctions may provide a means of informational or metabolic coupling between cells, may serve a structural role as scaffolding in the deposition and orientation of extracellular materials, or may be involved in the early stages of angiogenesis.
