It remains unknown, for example, why limb swelling resulting from surgical injury resolves initially, but recurs in some cases months or years later. Finding answers for these basic questions has been hampered by the lack of adequate animal models. In the current study, we used\n                    <jats:italic>Cre-lox<\/jats:italic>\n                    mice that expressed the human diphtheria toxin receptor (DTR) driven by a lymphatic-specific promoter in order to noninvasively ablate the lymphatic system of the hind limb. Animals treated in this manner developed lymphedema that was indistinguishable from clinical lymphedema temporally, radiographically, and histologically. Using this model and clinical biopsy specimens, we show that the initial resolution of edema after injury is dependent on the formation of collateral capillary lymphatics and that this process is regulated by M2-polarized macrophages. In addition, we show that despite these initial improvements in lymphatic function, persistent accumulation of CD4\n                    <jats:sup>+<\/jats:sup>\n                    cells inhibits lymphangiogenesis and promotes sclerosis of collecting lymphatics, resulting in late onset of edema and fibrosis. Our findings therefore provide strong evidence that inflammatory changes after lymphatic injury play a key role in the pathophysiology of lymphedema.\n                  <\/jats:p>","DOI":"10.1172\/jci.insight.84095","type":"journal-article","created":{"date-parts":[[2016,9,21]],"date-time":"2016-09-21T11:01:06Z","timestamp":1474455666000},"source":"Crossref","is-referenced-by-count":45,"title":["Diphtheria toxin\u2013mediated ablation of lymphatic endothelial cells results in progressive lymphedema"],"prefix":"10.1172","volume":"1","author":[{"given":"Jason C.","family":"Gardenier","sequence":"first","affiliation":[{"name":"Department of Surgery, Division of Plastic and Reconstructive Surgery, Memorial Sloan Kettering Cancer Center (MSKCC), New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey E.","family":"Hespe","sequence":"additional","affiliation":[{"name":"Department of Surgery, Division of Plastic and Reconstructive Surgery, Memorial Sloan Kettering Cancer Center (MSKCC), New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raghu P.","family":"Kataru","sequence":"additional","affiliation":[{"name":"Department of Surgery, Division of Plastic and Reconstructive Surgery, Memorial Sloan Kettering Cancer Center (MSKCC), New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ira L.","family":"Savetsky","sequence":"additional","affiliation":[{"name":"Department of Surgery, Division of Plastic and Reconstructive Surgery, Memorial Sloan Kettering Cancer Center (MSKCC), New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy S.","family":"Torrisi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Division of Plastic and Reconstructive Surgery, Memorial Sloan Kettering Cancer Center (MSKCC), New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriela D.
