METHODS: Calvarial osteoblasts of neonate rats were cultured under conditions of normal gravity(1G) and simulated weightlessness induced by clinostat respectively. The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits.

培养的大鼠乳鼠颅骨成骨随机分为对照组和失重组，在实验的24， 48和72 h提取细胞总RNA，进行反转录PCR，检测整合素的α5，αv和β1亚单位mRNA表达，并计算与内参照β肌动蛋白 beta？？？？
