Description:
A cell line has been established in continuous culture of human cerebral cortical neurons obtained from a patient with unilateral megalencephaly, a disorder associated with continued proliferation of immature neuronal cells. When differentiated in the presence of nerve growth factor, 1-isobutyl-3-methylxanthine, and dibutyryl adenosine 3',5'-monophosphate (cAMP), the cells display mature neuronal morphology with numerous long, extensively branched processes with spines and varicosities. The cells stain positively for neurofilament protein and neuron-specific enolase (selective neuronal markers) but are negative for glial markers, such as glial fibrillary acidic protein, S-100, and myelin basic protein. The cells also stain positively for the neurotransmitters gamma-aminobutyric acid (GABA), glutamate, somatostatin, cholecystokinin-8, and vasoactive intestinal polypeptide. These cells may facilitate characterization of neurons in the human central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ronnett, G V -- Hester, L D -- Nye, J S -- Connors, K -- Snyder, S H -- DA 00074/DA/NIDA NIH HHS/ -- DA 00266/DA/NIDA NIH HHS/ -- MH 18501/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 May 4;248(4955):603-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1692158" target="_blank"〉PubMed〈/a〉
