For IHC, a whole pulp tissue was excavated from the pulp chamber, and it was formalin-fixed and processed for routine IHC with angiogenic markers anti-VEGF, anti-Ang1, and anti-Ang2. Staining was visualized with diaminobenzidine (DAB), and examined using light microscopy. The distribution of markers in healthy and inflamed pulps was qualitatively and quantitatively analyzed. Real-time quantitative polymerase chain reaction (RT qPCR) was used to ascertain the gene expression levels of ANGPT1, ANGPT2, and TEK in the presence of inflammation. Statistical analysis was performed using the Mann\u2013Whitney test with the statistical significance level set at 0.05.Results: There was increased protein and mRNA expression of VEGF and Ang-1 markers in inflamed pulp samples as compared with that in the healthy pulp tissue. IHC demonstrated intense expression of the VEGF protein on endothelial cells (EC) and some non-ECs, and there was significantly more staining on ECs associated with inflamed tissue (P<\/jats:p>","DOI":"10.14744\/eej.2019.26349","type":"journal-article","created":{"date-parts":[[2019,2,12]],"date-time":"2019-02-12T07:25:10Z","timestamp":1549956310000},"page":"80-85","source":"Crossref","is-referenced-by-count":6,"title":["Vascularity and Angiogenic Signaling in the Dentine-Pulp Complex of Immature and Mature Permanent Teeth"],"prefix":"10.65717","volume":"4","author":[{"given":"Lara","family":"Friedlander","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trudy","family":"Milne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haizal Mohd","family":"Hussaini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedict","family":"Seo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alison","family":"Rich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmad","family":"Al-Hassiny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"55248","published-online":{"date-parts":[[2019,4,4]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/80\/80","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/80\/80","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:36:55Z","timestamp":1769085415000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/80"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,4,4]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,4,4]]}},"URL":"https:\/\/doi.org\/10.14744\/eej.2019.26349","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,4,4]]}}}
