ABSTRACT
OBJECTIVE:
To investigate the effects of emdogain, enamel matrix derivative (EMD), on the proliferation, cell cycle, mineralization and ultrastructure of human periodontal ligament (PDL) cells in vitro.METHODS:
The influence of cell growth on PDL cells was evaluated by Cell Counting Kit-8 (CCK-8) in the presence and absence of emdogain, after 1, 3, and 5 d of culture. DNA synthesis and ultrastructure of PDL cells were observed by flow cytometry(FCM) and transmission electron microscopy (TEM) in the presence and absence of emdogain after 3 d of culture. The increasing of osteogenic capacity was verified by the expression changes of osteogenic differentiation markers of bone sialoprotein (BSP) and osteopontin (OPN) in emdogain-treated PDL cells by immunohistochemicl staining.RESULTS:
Incubation of PDL cells with emdogain after 3 d significantly stimulated cell growth and DNA synthesis. Emdogain enhanced the osteogenic potential of PDL cells by high expression of osteogenic differentiation markers of BSP and OPN.CONCLUSION:
The data indicate that Emdogain enhances cell proliferation and promotes differentiation of PDL cells, which contributes to periodontal tissue regeneration .
