title: Distribution of Thy-1 differentiation alloantigen in the rat nervous system and in a cell line derived from a rat peripheral neurinoma.
abstract: The expression of the Thy-l 'differentiation alloantigen' was analyzed in rat tissues of two strains. Cerebrum was shown to express an amount of Thy-l equivalent to the thymus. The cerebellum, brain stem and spinal cord expressed approximately one-half this amount, and the olfactory bulb expressed 10- to 15-fold less. Of the peripheral nervous system tissues examined, only cauda equina expressed substantial amounts of Thy-l, although minor amounts were found on the lumbar roots and trigeminal nerve. Kidney, spleen, liver, salivary gland and testes expressed little or no Thy-l. Several cell lines derived from nervous system tumors were also examined. RN-l, a line established from a rat peripheral neurinoma, expressed Thy-l at levels comparable to thymus.
