Colocalization of tenascin with versican, a hyaluronate-binding chondroitin sulfate proteoglycan.

Journal Article

Rabbit antisera against tenascin, a large extracellular matrix protein, in conjunction with monoclonal antibodies of mouse origin against versican, a large hyaluronate-binding proteoglycan, were used to make a comparative study of the distribution of the two antigens in the same cryostat sections by double immunofluorescence. In the central nervous system, tenascin was invariably associated with versican, but the reverse was not true, in that versican was also found where tenascin was not detectable, particularly in gray matter. There were major species differences in the distribution of tenascin in the central nervous system. In the cow, tenascin was found in cerebral and spinal cord white matter and in the granule cell layer of the cerebellum. In the human brain, tenascin was found in cerebral white matter but not in the cerebellum. In the rat, tenascin was mainly confined to brain periventricular layer and spinal cord white matter. During the development of the cerebellum of the rat, the tenascin immunoreactivity decreased, and a lower molecular weight band appeared (J1-160/180/restrictin?) and persisted throughout adulthood. Tenascin expression was a relatively late event in the development of the rat central nervous system, immunoreactivity being first observed after birth. In the rat embryo, tenascin was found to co-localize with versican in precartilaginous mesenchyme and in connective tissue underlying epithelia. The colocalization of versican with tenascin suggests that versican may be the tenascin (cytotactin)-associated proteoglycan reported in the literature.
