Striatal matrix neurons of the rat differentiate in culture from dissociated fetal progenitor cells isolated by buoyant density centrifugation Academic Article uri icon

abstract

  • The adult striatum is composed of interlacing compartments known as patches (striosomes) and matrix, which differ with respect to a host of architectonic, biochemical and developmental parameters. We have exploited the 2-phase development of the striatum, employing buoyant-density fractionation to separate proliferating/undifferentiated neural precursors from the differentiated neurons of the E19 striatum. Primary cell cultures were established for the collected fractions, and immunohistochemistry for maturational and compartment-specific markers performed. The results indicate that the least buoyant, striatal precursors concentrate principally in the low buoyancy fraction of the gradient, and in culture express known matrix phenotype markers in an appropriate time frame.
