    Description: Genes associated with Hirschsprung disease, a failure to form enteric ganglia in the hindgut, were highly up-regulated in gut neural crest stem cells relative to whole-fetus RNA. One of these genes, the glial cell line-derived neurotrophic factor (GDNF) receptor Ret, was necessary for neural crest stem cell migration in the gut. GDNF promoted the migration of neural crest stem cells in culture but did not affect their survival or proliferation. Gene expression profiling, combined with reverse genetics and analyses of stem cell function, suggests that Hirschsprung disease is caused by defects in neural crest stem cell function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2614078/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2614078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iwashita, Toshihide -- Kruger, Genevieve M -- Pardal, Ricardo -- Kiel, Mark J -- Morrison, Sean J -- CA46592/CA/NCI NIH HHS/ -- DK58771/DK/NIDDK NIH HHS/ -- NIH5P60-DK20572/DK/NIDDK NIH HHS/ -- P30 AR48310/AR/NIAMS NIH HHS/ -- P60-AR20557/AR/NIAMS NIH HHS/ -- R01 NS040750/NS/NINDS NIH HHS/ -- R01 NS040750-01/NS/NINDS NIH HHS/ -- R01 NS40750-01/NS/NINDS NIH HHS/ -- R21 HD40760-02/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):972-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Internal Medicine, University of Michigan, Ann Arbor, MI 48109-0934, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12920301" target="_blank"〉PubMed〈/a〉

    Description: Epidermal growth factor (EGF) is a potent polypeptide mitogen originally isolated from the adult male mouse submaxillary gland. It also acts as a gastrointestinal hormone. EGF-immunoreactive material has recently been identified within neuronal fibers and terminals in rodent brain. In the present study, EGF was found to enhance survival and process outgrowth of primary cultures of subneocortical telencephalic neurons of neonatal rat brain in a dose-dependent manner. This effect was observed with EGF concentrations as low as 100 picograms per milliliter (0.016 nanomolar) and was dependent on the continuous presence of EGF in the medium. Similar effects were observed with basic fibroblast growth factor, but several other growth-promoting substances, including other mitogens for glial elements, were without effect. Thus EGF, in addition to its mitogenic and hormonal activities, may act as a neurite elongation and maintenance factor for select neurons of the rodent central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrison, R S -- Kornblum, H I -- Leslie, F M -- Bradshaw, R A -- NS19319/NS/NINDS NIH HHS/ -- NS19964/NS/NINDS NIH HHS/ -- T32-CA0905A/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Oct 2;238(4823):72-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, College of Medicine, University of California, Irvine 92717.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3498986" target="_blank"〉PubMed〈/a〉

    Description: In density-arrested monolayer cultures of Balb/c 3T3 cells, platelet-derived growth factor (PDGF) stimulates expression of the c-myc and c-fos proto-oncogenes, as well as the functionally uncharacterized genes, JE, KC, and JB. These genes are not coordinately regulated. Under ordinary conditions, c-fos, JE, KC, and JB respond to PDGF only when the cells are in a state of G0 growth arrest at the time of PDGF addition. The c-myc gene is regulated in opposition to the other genes, responding best to PDGF in cycling cultures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rollins, B J -- Morrison, E D -- Stiles, C D -- CA 20042-09/CA/NCI NIH HHS/ -- GM 31489-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 27;238(4831):1269-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Medicine, Dana-Farber Cancer Institute, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685976" target="_blank"〉PubMed〈/a〉

    Description: Both elemental distribution and ion transport in cultured cells have been imaged by ion microscopy. Morphological and chemical information was obtained with a spatial resolution of approximately 0.5 micron for sodium, potassium, calcium, and magnesium in freeze-fixed, cryofractured, and freeze-dried normal rat kidney cells and Chinese hamster ovary cells. Ion transport was successfully demonstrated by imaging Na+-K+ fluxes after the inhibition of Na+- and K+ -dependent adenosine triphosphatase with ouabain. This method allows measurements of elemental (isotopic) distribution to be related to cell morphology, thereby providing the means for studying ion distribution and ion transport under different physiological, pathological, and toxicological conditions in cell culture systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandra, S -- Morrison, G H -- R01GM24314/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 28;228(4707):1543-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2990033" target="_blank"〉PubMed〈/a〉
