1·Methods BMSCs were co-cultured with cementum slices and femora slices in vitro, to detect with light microscope at 7 day and 28 day, and to determine ALP activity.
方法将骨髓基质细胞与牙骨质片和股骨片在体外共同培养，分别在第7天、第28天进行光镜观察及碱性磷酸酶的测定。
2·Enamel matrix protein is secreted by Hertwig's epithelial root sheath and is responsible for initiating the original formation of acellular cementum on the developing tooth root.
釉质基质蛋白由Hert wigs上皮根鞘分泌，能诱导发育牙根上的非细胞牙骨质的初期成形。
3·The periodontal ligament is a connective tissue located between the cementum of teeth and the alveolar bone of the mandibula.
牙周膜是位于牙骨质和下颌骨的齿槽骨之间的结缔组织。
4·It is well know that the biological basis of Orthodontics is the plasticity of jaw, the strength-proof of cementum and the stability of periodontal ligament internal environment.
口腔正畸学的生物学基础在于颌骨的可塑性、牙骨质的抗压性及牙周膜内环境的稳定性。
