Objective: The interaction of cell and medical biomaterial is one of the significant factors to affect clinical application of medical biomaterial.This research is to investigate three of suture lines how to affect the proliferation and cell cycle of lung adenocarcinoma cell A549 in vitro.Methods: Three of suture lines were respectively cultivated with lung adenocarcinoma cell A549,after of 72 hours,we detected absorptions of each group by MTT method in order to reflect the proliferation of lung adenocarcinoma cell A549,and also examined percentage of G1 period cells and S period cells of each group by flow cytometry.Results: Different of suture lines had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 (P < 0.05).The effect of absorbent suture line was the strongest on the proliferation and cell cycle of lung adenocarcinoma cell A549,the effect of chorda serica chirurgicalis was medium,and the effect of slide wire was poor.Different length of each suture line had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 (P < 0.05).Conclusion: Three of suture line materials have different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549,with dose-effect relationship.
Objective: The interaction of cell and medical biomaterial is one of the significant factors to affect clinical application of medical biomaterial. This research is to investigate three of suture lines how to affect the proliferation and cell cycle of lung adenocarcinoma cell A549 in vitro. Methods: Three of suture lines were acquired cultivated with lung adenocarcinoma cell A549, after of 72 hours, we detected absorptions of each group by MTT method in order to reflect the proliferation of lung adenocarcinoma cell A549, and also examined percentage of G1 period cells and S period cells of each group by flow cytometry. Results: Different of suture lines had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 (P <0.05). The effect of absorbent suture line was the strongest on the proliferation and cell cycle of lung adenocarcinoma cell A549, the effect of chorda serica chirurgicalis was medium, and the effect of slide wire was poor. Different length of each suture line had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 (P <0.05). Conlusion: Three of suture line materials have different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549, with dose-effect relationship.
