GAP-JUNCTIONS BETWEEN FIBROBLASTS IN RAT MYOTENDON

We applied conventional and freeze-fracture electron microscopy to stu dy intercellular contacts between the processes of fibroblasts in the myotendon of the rat exterior digitorium longus. The results showed we ll defined gap junctions between the cell processes, while other cell junctional structures such as tight junctions and desmosomes were not recognizable, The present study suggests that the gap junctions repres ent a structure to coordinate the activities of fibroblasts distribute d in the myotendon of the muscle.
