In contrast, much smaller acute changes killed the cells previously studied in tissue culture, such as mouse IM collecting duct 3 (mIMCD3) cells, that are immortalized with SV40 and proliferate rapidly. Proliferation and DNA replication sensitize mIMCD3 cells to hypertonicity. In the present studies, we observed that proliferating cells were scarce in rat IM. Then, we prepared passage 2 mouse IM epithelial (p2mIME) cells. They have a much lower incidence of DNA replication than do mIMCD3 cells. p2mIME cells survive much greater acute increases in NaCl than do mIMCD3 cells and also tolerate significantly greater acute increases of urea and of NaCl plus urea, but still not to levels as high as occur in vivo. We conclude that immortalization and continued DNA replication account for part of the previously observed difference in osmotic tolerance between IM cells in vivo and in cell culture but that other factors must also be involved.<\/jats:p>","DOI":"10.1152\/ajprenal.00038.2002","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:35:38Z","timestamp":1425414938000},"page":"F302-F308","source":"Crossref","is-referenced-by-count":30,"title":["Proliferation and osmotic tolerance of renal inner medullary epithelial cells in vivo and in cell culture"],"prefix":"10.1152","volume":"283","author":[{"given":"Zheng","family":"Zhang","sequence":"first","affiliation":[{"name":"Laboratory of Kidney and Electrolyte Metabolism, National Heart Lung and Blood Institute, Bethesda, Maryland 20892;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Cai","sequence":"additional","affiliation":[{"name":"Laboratory of Kidney and Electrolyte Metabolism, National Heart Lung and Blood Institute, Bethesda, Maryland 20892;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis","family":"Michea","sequence":"additional","affiliation":[{"name":"Laboratory of Kidney and Electrolyte Metabolism, National Heart Lung and Blood Institute, Bethesda, Maryland 20892;"},{"name":"Laboratory of Cellular and Molecular Physiology, Faculty of Medicine, Universidad de los Andes, San Carlos Apoquindo 2200, Santiago, Chile; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia I.","family":"Dmitrieva","sequence":"additional","affiliation":[{"name":"Laboratory of Kidney and Electrolyte Metabolism, National Heart Lung and Blood Institute, Bethesda, Maryland 20892;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Andrews","sequence":"additional","affiliation":[{"name":"Department of Cell Biology, Georgetown University Medical Center, Washington, District of Columbia 20002"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurice B.","family":"Burg","sequence":"additional","affiliation":[{"name":"Laboratory of Kidney and Electrolyte Metabolism, National Heart Lung and Blood Institute, Bethesda, Maryland 20892;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1177\/41.1.7678022"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M000522200"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.2001.281.3.F522"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1996.270.4.F575"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.2000.278.2.F209"},{"key":"B8","doi-asserted-by":"crossref","first-page":"2565","DOI":"10.1681\/ASN.V12122565","volume":"12","author":"Neuhofer W","year":"2001","journal-title":"J Am Soc Nephrol"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1007\/s004240050531"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1993.265.3.F416"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1998.274.6.F1167"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2001.060002553.x"}],"container-title":["American Journal of Physiology-Renal Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/ajprenal.00038.2002","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,1]],"date-time":"2022-05-01T09:34:52Z","timestamp":1651397692000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/ajprenal.00038.2002"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,8,1]]},"references-count":10,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2002,8,1]]}},"alternative-id":["10.1152\/ajprenal.00038.2002"],"URL":"https:\/\/doi.org\/10.1152\/ajprenal.00038.2002","relation":{},"ISSN":["1931-857X","1522-1466"],"issn-type":[{"value":"1931-857X","type":"print"},{"value":"1522-1466","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,8,1]]}}}
