[The effects of fibronectin on the attachment and proliferation of periodontal ligament cells].
The purpose of this in vitro study was to observe and evaluate the effects of fibronectin(FN) on the growth of periodontal ligament cells(PDLC) on different root surfaces. Cell culture and scanning electronic microscopic techniques were used. The results showed that the growth pattern of PDLC on normal root surfaces were better than that of periodontitis. FN can significantly enhanced the attachment and proliferation of PDL cells on normal root surfaces. On the other hand, only the enhancement of attachment by FN was observed on the periodontitis root surfaces. It may be concluded that FN can promote the growth of PDLC and FN may play different effects on the attachment and proliferation of PDLC.
