The fragmentation is similar to that observed in other types of cells undergoing apoptosis or programmed cell death. In this study we describe a more comprehensive approach to the study of DNA fragmentation in leukaemia. Fragmentation was observed in freshly isolated cells from patients with T\u2010cell acute lymphoblastic leukaemia and in one with common acute lymphoblastic leukaemia. Frozen samples of T\u2010cell acute lymphoblastic leukaemia, common acute lymphoblastic leukaemia, and acute myeloid leukaemia cells also showed fragmentation of DNA. However, no fragmentation was evident in normal leukocytes treated under the same conditions. Ultrastructural studies on the isolated leukaemia cells demonstrate that the chromatin cleavage observed biochemically is associated with morphological changes characteristic of apoptosis.<\/jats:p>","DOI":"10.1002\/path.1711580207","type":"journal-article","created":{"date-parts":[[2005,6,22]],"date-time":"2005-06-22T09:42:57Z","timestamp":1119433377000},"page":"123-129","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["Cell death by apoptosis in acute leukaemia"],"prefix":"10.1002","volume":"158","author":[{"given":"Glenn D.","family":"Baxter","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Russell J.","family":"Collins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian V.","family":"Harmon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sharad","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roger L.","family":"Prentice","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter J.","family":"Smith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin F.","family":"Lavin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,6,15]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"453","article-title":"Studies of cellular injury in isolated flounder tubules.
