Single cell suspensions, prepared from brain stem, cerebellum, and forebrain parenchyma of embryonic and adult mice, were plated on monolayers of an astroglial cell line derived from a spontaneously immortalized mouse cerebellar culture, the D19 clone. A few of the brain cells adhering to the D19 monolayers were immunoreactive to the Mac-1 antibody, which(More)
We have previously reported that astroglial cell lines derived from spontaneously immortalized mouse cerebellar cultures as well as primary astrocyte cultures express the mRNA of the alpha isoform of smooth muscle actin. In this report, we have used an antiserum specific for the alpha smooth muscle actin protein to investigate the presence and the pattern(More)
Reduction of the delta 7 double bond of sterols, a key biosynthetic step in higher eukaryotes, is lacking in lower eukaryotes like the yeast Saccharomyces cerevisiae, leading to terminal sterols with a delta 5,7-conjugated diene structure. Genes encoding two sterol reductases involved, respectively, in the reduction of sterol delta 14 and delta 24(28)(More)
Astrocytes belong to the glial cell population and represent a major subclass of the CNS. Although different subtypes of astrocytes have been described according to their morphological characteristics, biochemical markers of each subtype of astrocytes are not yet available. We have thus undertaken to compare gene expression pattern of different astroglial(More)
The CNS is composed of neurons and glial cells (i.e., astrocytes, oligodendrocytes, and microglia). The brain communicates with the blood circulation through choroid plexus and meninges as well as through the blood-brain barrier. To identify transcripts specifically expressed in a distinct brain cell type, we have previously constructed a subtracted cDNA(More)
