Objective To investigate the effects of simulated weightlessness on cell area, cell multiplication and cell cycle of MG-63 cells.
细胞生长曲线显示模拟失重后细胞增殖明显受抑制。
Methods: the osteoblast-like cell MG-63 were stimulated with different amplitude by four-point-bend loading device, and the different proliferative index after tension-stress load were studied.
方法：采用四点弯曲细胞力学加载仪对成骨样细胞MG - 6 3分别以不同强度的张应力进行力学刺激，并对其受力后的增殖状态进行了研究。
Results: in human osteosarcoma cell line MG-63 culture Type I collagen mRNA expression reach a maximum level on days 7.
结果：人成骨肉瘤MG - 63细胞株接种培养第7天后I型胶原基因表达较高。
