title: [A contribution to the origin of ganglia. A study of light-, immunofluorescence-, and electronmicroscopic changes (author's transl)].
abstract: 10 ganglia were studied by means of light and electrone microscope and with immunfluorescence methods. The light microscopic findings in the wall of a ganglion resemble on developing hygroma. The mesenchymal cells ultrastructurally show differentiation to synovia-like cells, either surrounding the ganglion in the connective tissue wall or lining the cavity. The development of synovial tissue from undifferentiated mesenchymal cells is due to the typical mechanical stimulus affecting joints.
