Six days later, ACPs (characterized in vitro prior to implantation) or culture media were injected directly into the ischaemic myocardial region or into the coronary artery via the aorta. Cardiac function was measured by echocardiography prior to and at 2 and 4 weeks after implantation. Scar morphology, cell engraftment, and myocardial angiogenesis were evaluated at 4 weeks. Two and four weeks after implantation, cardiac function declined in both of the control groups but improved in both the intramyocardial and intracoronary ACP groups. Significant reductions in myocardial scar area were only observed in the intramyocardial ACP group, while increases in blood vessel density, which were observed in all ACP recipients, were greatest in the intracoronary ACP group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Human ACPs, delivered via intramyocardial or intracoronary injection, engrafted into damaged cardiac tissue and improved cardiac function within 4 weeks through effects on scar morphology and blood vessel formation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.ejheart.2008.04.004","type":"journal-article","created":{"date-parts":[[2008,5,20]],"date-time":"2008-05-20T05:08:53Z","timestamp":1211260133000},"page":"525-533","source":"Crossref","is-referenced-by-count":15,"title":["Human Angiogenic Cell Precursors Restore Function in the Infarcted Rat Heart: A Comparison of Cell Delivery Routes"],"prefix":"10.1093","volume":"10","author":[{"given":"Zhuo","family":"Sun","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Wu","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroko","family":"Fujii","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiang","family":"Wu","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shu-Hong","family":"Li","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana","family":"Porozov","sequence":"additional","affiliation":[{"name":"TheraVitae Ltd , Ness Ziona ,","place":["Israel"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adina","family":"Belleli","sequence":"additional","affiliation":[{"name":"TheraVitae Ltd , Ness Ziona ,","place":["Israel"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentin","family":"Fulga","sequence":"additional","affiliation":[{"name":"TheraVitae Ltd , Ness Ziona ,","place":["Israel"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yael","family":"Porat","sequence":"additional","affiliation":[{"name":"TheraVitae Ltd , Ness Ziona ,","place":["Israel"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ren-Ke","family":"Li","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Toronto General Research Institute, Toronto General Hospital and University of Toronto , Toronto, Ontario ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2014,1,13]]},"reference":[{"key":"2026020203430276500_ejhf2008-04-004-bib-0001","doi-asserted-by":"crossref","first-page":"1114","DOI":"10.1161\/01.CIR.97.12.1114","article-title":"Constitutive expression of phVEGF165 after intramuscular gene transfer promotes collateral vessel development in patients with critical limb ischemia","volume":"97","author":"Baumgartner","year":"1998","journal-title":"Circulation"},{"key":"2026020203430276500_ejhf2008-04-004-bib-0002","doi-asserted-by":"crossref","first-page":"623","DOI":"10.1172\/JCI117378","article-title":"Basic fibroblast growth factor improves myocardial function in chronically ischemic porcine hearts","volume":"94","author":"Harada","year":"1994","journal-title":"J Clin Invest"},{"key":"2026020203430276500_ejhf2008-04-004-bib-0003","doi-asserted-by":"crossref","first-page":"671","DOI":"10.1038\/386671a0","article-title":"Mechanisms of angiogenesis","volume":"386","author":"Risau","year":"1997","journal-title":"Nature"},{"key":"2026020203430276500_ejhf2008-04-004-bib-0004","doi-asserted-by":"crossref","first-page":"662","DOI":"10.1172\/JCI117018","article-title":"Therapeutic angiogenesis.
