    Abstract

    AIM: To obtain intestinal pacemaker cells through dissection of the myenteric plexus of mouse jejunum, and to identify interstitial cells of Cajal (ICC) AP through selective staining with methylene blue for further electrophysiological study.

    METHODS: Jejunum was removed from newborn CD-1 mice. The longitudinal muscle layer containing the myenteric plexus was cut into small pieces for culture. Live cells were stained with methylene blue and c-kit antibody.

    RESULTS: Cells grown from explant culture and characterized by phenotypic features were identified as pacemaker cells, i.e. ICC-AP. Cells stained with methylene blue were also positive for c-kit antibody, whereas live neurons, smooth muscle cells and other types of ICC were not stained with methylene blue.

    CONCLUSION: Pacemaker cells, i.e. ICC-AP, can be obtained through selective dissection. Methylene blue can be used for live staining identification of ICC-AP and, therefore, provides a model for further functional study.

    Key Words: Jejunum; Interstitial cells of Cajal; Explant culture; Methylene blue ......
