We can stimulate bone formation with tensile stress on a suture of mouse calvaria. Gene expressions of many factors, especially Wnt/beta-catenin family which are involved in bone-cell activity were examined during the stimulated bone formation. We could show the relative expression ratios of some factors at each time point of the experiment. Those results suggested which factors were more important at each stage of the stimulated bone formation.

我们可以在小鼠颅骨缝合线上施加拉伸应力来刺激骨形成。在刺激骨形成过程中，研究了许多因子的基因表达，特别是参与骨细胞活性的Wnt/ β -连环蛋白家族。我们可以显示出一些因子在实验的每个时间点的相对表达率。这些结果表明哪些因素在刺激骨形成的每个阶段更重要。
