Resumen: | Studies in vitro have permitted the identification of enteric neural progenitor cells. Now the question arises as to where these progenitor cells are located in vivo. The purpose of this paper is to identify possible candidate cells by means of transmission electron microscopy (TEM). We have located three interstitial cellular types around the rat duodenum myenteric plexus. Type I cells have been identified as Interstitial Cells of Cajal (ICCs). These cells present well defined ultrastructural characteristics, including the triple connexion ICnervous trunk- blood vessels. Type II cells show characteristics of immature cells, emphasizing the presence of a single cilium with the structure (9+0). To analyse this nanostructure, we have elaborated a reconstruction on ultrathin sections. The two previously described cellular types could be considered to be different functional states of the same cell. Type III cells present ultrastructural characteristics of fibroblast-like cells. This study suggests that Type II cells could be a source of neural progenitor cells. |
