Layers resembling AEFC were also deposited along the inner wall of the alveolar bone. At the time of observation (six weeks after being wounded), cells other than fibroblast-like cells could not be distinguished close to the newly formed AEFC-like layers. We suggest that the deposition of this material was related to the activity of periodontal ligament fibroblasts.<\/jats:p>","DOI":"10.1177\/00220345900690100801","type":"journal-article","created":{"date-parts":[[2010,11,28]],"date-time":"2010-11-28T21:14:56Z","timestamp":1290978896000},"page":"1669-1673","source":"Crossref","is-referenced-by-count":46,"title":["Formation of Acellular Root Cementum in to Dental and Non-dental Hard Tissues in the Rat"],"prefix":"10.1177","volume":"69","author":[{"given":"W.","family":"Beertsen","sequence":"first","affiliation":[{"name":"Experimental Orat Biology Group, Department of Periodontology, Academic Centre for Dentistry Amsterdam (ACTA), Louwesweg 1, 1066 EA Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Everts","sequence":"additional","affiliation":[{"name":"Department of Cell Biology and Histology, Faculty of Medicine, University of Amsterdam"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1990,10,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0765.1983.tb00361.x"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0765.1982.tb01185.x"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/S0934-8832(89)80035-6"},{"key":"atypb4","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1177\/00220345900690100801","volume":"69","author":"Beertsen, W.","year":"1990","journal-title":"J Dent Res"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1092230214"},{"key":"atypb6","unstructured":"Freeman, E.
