These complications can propagate even more precipitously in the setting of common concomitant diseases in patients with CLTI such as diabetes mellitus (DM). CLTI ulcers are cutaneous, non-healing wounds that persist due to the reduced perfusion and dysfunctional neovascularization associated with severe PAD. Existing therapies for CLTI are primarily limited to anatomic revascularization and medical management of contributing factors such as atherosclerosis and glycemic control. However, many patients fail these treatment strategies and are considered \u201cno-option,\u201d thereby requiring extremity amputation, particularly if non-healing wounds become infected or fulminant gangrene develops. Given the high economic burden imposed on patients, decreased quality of life, and poor survival of no-option CLTI patients, regenerative therapies aimed at neovascularization to improve wound healing and limb salvage hold significant promise. Cell-based therapy, specifically utilizing mesenchymal stem\/stromal cells (MSCs), is one such regenerative strategy to stimulate therapeutic angiogenesis and tissue regeneration. Although previous reviews have focused primarily on revascularization outcomes after MSC treatments of CLTI with less attention given to their effects on wound healing, here we review advances in pre-clinical and clinical studies related to specific effects of MSC-based therapeutics upon ischemic non-healing wounds associated with CLTI.<\/jats:p>","DOI":"10.3389\/fcvm.2023.1113982","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T08:12:04Z","timestamp":1675239124000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":48,"title":["Mesenchymal stem cell-based therapy for non-healing wounds due to chronic limb-threatening ischemia: A review of preclinical and clinical studies"],"prefix":"10.3389","volume":"10","author":[{"given":"Carlos Theodore","family":"Huerta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca A.","family":"Voza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulexi Y.","family":"Ortiz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhao-Jun","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omaida C.","family":"Velazquez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,2,1]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1425","DOI":"10.1161\/CIR.0b013e31828b82aa","article-title":"Management of patients with peripheral artery disease (compilation of 2005 and 2011 ACCF\/AHA guideline recommendations): a report of the American College of Cardiology Foundation\/American Heart Association task force on practice guidelines","volume":"127","author":"Anderson","year":"2013","journal-title":"Circulation"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"686","DOI":"10.1016\/j.jvs.2014.03.290","article-title":"Epidemiology of peripheral arterial disease and critical limb ischemia in an insured national population","volume":"60","author":"Nehler","year":"2014","journal-title":"J.
