The primary cilium of telocytes in the vasculature: electron microscope imaging.

Cantarero I, Luesma MJ, Junquera C - J. Cell. Mol. Med. (2011)

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.

(A) Duodenal arteriole from Wistar rat. Positive immunostaining to CD117/c-kit in perivascular localization. Inset: Cell with fusiform body is intensely c-kit positive. (B) Positive control in rat jejunum. Nuclei were counterstained with Mayer haematoxylin. ar: arteriole.

fig01: (A) Duodenal arteriole from Wistar rat. Positive immunostaining to CD117/c-kit in perivascular localization. Inset: Cell with fusiform body is intensely c-kit positive. (B) Positive control in rat jejunum. Nuclei were counterstained with Mayer haematoxylin. ar: arteriole.

Mentions: By immunohistochemistry, cell expressing the stemness marker c-kit could be found in all the types of blood vessels studied: arterioles, venules and capillaries. c-kit was expressed in cells located just behind the muscle layer surrounding blood vessels (Fig. 1A). Sections containing archetypal myenteric plexus interstitial cell of Cajal (ICC-MP) from the digestive tract were used as positive controls (Fig. 1B).
