    Pattern analysis of gap junction plaques with open and closed pores
    (1985) Müller, A.; Blanz, Wolf-Ekkehard; Laub, Gerhard; Hülser, Dieter F.
    The structure of freeze-fractured gap junctions was studied by electron microscopy and subsequent pattern analysis using a computer controlled image processing system. Rat mammary tumor cells (BICR/WIR-k) which are permanently coupled via gap junctions when cultered as monolayers were used under different fixed and unfixed conditions. Active (coupling competent) gap junctions seem to be characterized by loosely packed connexons, whereas non-active (permanently closed) gap junctions may consist of tightly packed particles.
