However, there is limited literature examining the bone in chronic rhinosinusitis (CRS) pathology. In this study we cultured osteoblasts from bone harvested during sinus surgery as well as from nondiseased controls to compare their cellular properties.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sinus bone was collected during sinus and skull\u2010base surgery and placed in proliferation media. Outgrowth of cells occurred at 2 weeks and the cells were confirmed to be osteoblasts by alkaline phosphatase staining. Cellular adhesion was determined by replating and counting adhered cells at 4 hours. Proliferation of cells plated for 24 hours was assayed by measuring [<jats:sup>3<\/jats:sup>H]\u2010thymidine incorporation. Calcium content was measured by changing cells to differentiation media and measuring the calcium content on days 7, 14, and 21.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Alkaline phosphatase assay showed more than 90% of osteoblasts staining in all samples. Osteoblasts from patients with CRS had significant decreases in adhesion (<jats:italic>p<\/jats:italic> &lt; 0.01) compared to osteoblasts from skull\u2010base patients. There was a significant (<jats:italic>p<\/jats:italic> &lt; 0.05) increase in calcium content in rhinosinusitis samples compared with the nondiseased sinus bone samples.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>To date, this is the first known study that shows a direct comparison of osteoblast properties between patients with and without CRS. Our results indicate that there are fundamental phenotypic differences in adhesion and mineralization between osteoblasts in patients with CRS compared to controls.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21434","type":"journal-article","created":{"date-parts":[[2014,12,20]],"date-time":"2014-12-20T04:40:39Z","timestamp":1419050439000},"page":"124-131","source":"Crossref","is-referenced-by-count":9,"title":["Chronic rhinosinusitis osteoblasts differ in cellular properties from normal bone"],"prefix":"10.1002","volume":"5","author":[{"given":"Patrick R.","family":"Stevens","sequence":"first","affiliation":[{"name":"Department of Otolaryngology University of Connecticut Health Center  Farmington CT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Belachew","family":"Tessema","sequence":"additional","affiliation":[{"name":"Connecticut Sinus Institute  Farmington CT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seth M.","family":"Brown","sequence":"additional","affiliation":[{"name":"Connecticut Sinus Institute  Farmington CT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kourosh","family":"Parham","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology University of Connecticut Health Center  Farmington CT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gloria","family":"Gronowicz","sequence":"additional","affiliation":[{"name":"Department of Surgery University of Connecticut Health Center  Farmington CT"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,12,19]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/MOO.0b013e3282fdcc9a"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/00034894041130S502"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21057"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/hn.2003.v128.amhn0312811"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1398-9995.1989.tb02234.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11882-012-0250-y"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.2500\/105065801779954148"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200012000-00023"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200111000-00015"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.2500\/ajr.2006.20.2857"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-4486.2010.02218.x"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MOO.0b013e32835ac656"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/alr.20068"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.2038"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0385-8146(02)00098-6"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0736-0266(03)00155-4"},{"key":"e_1_2_6_18_1","first-page":"248","article-title":"Characteristics of primary osteoblast culture derived from rat fetal calvaria","volume":"15","author":"Ho ML","year":"1999","journal-title":"Kaohsiung J Med Sci"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/0955-0674(95)80110-3"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(92)90115-S"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004410100417"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.2500\/108854196778662246"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200211000-00008"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199804000-00008"}],"container-title":["International Forum of Allergy &amp; Rhinology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21434","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/alr.21434","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,5]],"date-time":"2023-10-05T21:02:21Z","timestamp":1696539741000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/alr.21434"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,12,19]]},"references-count":23,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2015,2]]}},"alternative-id":["10.1002\/alr.21434"],"URL":"https:\/\/doi.org\/10.1002\/alr.21434","archive":["Portico"],"relation":{},"ISSN":["2042-6976","2042-6984"],"issn-type":[{"value":"2042-6976","type":"print"},{"value":"2042-6984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,12,19]]}}}
