The<unk>  (ICC) is a type of<unk>  found in the gastrointestinal tract.  It serves as a pacemaker that triggers gut contraction.
Many types of smooth muscle tissues have now been shown to contain ICC, but with few exceptions the function of these<unk> s is not known and an area of active research. An international society (International Society for ICC, www.isicc.org) has recently been formed to provide a forum to discuss research in ICC in a variety of tissues.
