摘要:: Cells from the gingival lamina propria, bone-derived granular tissues and periodontal ligament (PDL) were isolated after periodontal surgery and subsequently cultured in vitro. The resulting cells were defined as gingival cells, bone cells and PDL cells, respectively. Under a phase contrast microscope, the cultured cells exhibited a spindle and/or a polyhedral shape. On the basis of their appearance under an electron microscope, spindle-shaped cells and polyhedral-shaped cells were identified as fibroblasts and osteoblasts, respectively. Bone cells, a homogeneous population of osteoblasts, had a more rapid growth ability than PDL cells, which were a heterogeneous population of fibroblasts and osteoblasts. Of particular interest was that only bone cells produced bone matrix in the multilayers in vitro. These results support the hypothesis that the phenotype expressed by cells from the alveolar bone establishes a new concept for progenitor cells in the formation of cementum.
