The primary cilium of telocytes in the vasculature: electron microscope imaging.
Bottom Line: The fine structure of the wall of blood vessels has been studied previously using the electron microscope, but the presence the telocytes associated with vasculature, a specific new cellular entity, has not been studied in depth.Interestingly, telocytes have been recently found in the epicardium, myocardium, endocardium, human term placenta, duodenal lamina propria and pleura.Here, the telocyte-blood vessels cell proximity, the relationship between telocytes, exosomes and nervous trunks may have a special significance.

Mentions: Using electron microscopy, we observed that telocytes have been clearly found in the loose connective tissue surrounding the arterioles, venules and capillaries. Telocytes associated with the vasculature were morphologically similar to those previously found in other locations. In arterioles, the telocytes often send telopodes bordering the tunica adventitia (Fig. 3A). The adjacent telopodes may establish junctional complexes (Fig. 3B) and show small dilatations (podoms) that accommodate rough endoplasmic reticulum (Fig. 3C). In relation to venules and capillaries, the telocytes were located parallel with the longitudinal axis of the smooth muscle cells of the vessel wall (Fig. 4A and B, respectively). Also, the telopodes can form a wide network around the blood vessels (Fig. 4C).
