    Segregation of human neural stem cells in the developing primate forebrain (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-07-28
    Description: Many central nervous system regions at all stages of life contain neural stem cells (NSCs). We explored how these disparate NSC pools might emerge. A traceable clone of human NSCs was implanted intraventricularly to allow its integration into cerebral germinal zones of Old World monkey fetuses. The NSCs distributed into two subpopulations: One contributed to corticogenesis by migrating along radial glia to temporally appropriate layers of the cortical plate and differentiating into lamina-appropriate neurons or glia; the other remained undifferentiated and contributed to a secondary germinal zone (the subventricular zone) with occasional members interspersed throughout brain parenchyma. An early neurogenetic program allocates the progeny of NSCs either immediately for organogenesis or to undifferentiated pools for later use in the "postdevelopmental" brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ourednik, V -- Ourednik, J -- Flax, J D -- Zawada, W M -- Hutt, C -- Yang, C -- Park, K I -- Kim, S U -- Sidman, R L -- Freed, C R -- Snyder, E Y -- New York, N.Y. -- Science. 2001 Sep 7;293(5536):1820-4.

    Purkinje cell degeneration (pcd) phenotypes caused by mutations in the axotomy-induced gene, Nna1 (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-09
    Description: The classical recessive mouse mutant, Purkinje cell degeneration (pcd), exhibits adult-onset degeneration of cerebellar Purkinje neurons, retinal photoreceptors, olfactory bulb mitral neurons, and selected thalamic neurons, and has defective spermatogenesis. Here we identify Nna1 as the gene mutated in the original pcd and two additional pcd alleles (pcd2J and pcd3J). Nna1 encodes a putative nuclear protein containing a zinc carboxypeptidase domain initially identified by its induction in spinal motor neurons during axonal regeneration. The present study suggests an unexpected molecular link between neuronal degeneration and regeneration, and its results have potential implications for neurodegenerative diseases and male infertility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fernandez-Gonzalez, Angeles -- La Spada, Albert R -- Treadaway, Jason -- Higdon, Jason C -- Harris, Belinda S -- Sidman, Richard L -- Morgan, James I -- Zuo, Jian -- CA 23944/CA/NCI NIH HHS/ -- CA21765/CA/NCI NIH HHS/ -- DC 04761/DC/NIDCD NIH HHS/ -- ES 10772/ES/NIEHS NIH HHS/ -- EY 12950/EY/NEI NIH HHS/ -- NS 40361/NS/NINDS NIH HHS/ -- RR 01183/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 8;295(5561):1904-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Neurobiology, St. Jude Children's Research Hospital, Memphis, TN 38105, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11884758" target="_blank"〉PubMed〈/a〉
