A study about the connection of the pattern of hair loss and the promoter environment of androgen receptor gene.

我们采集了一例脱发患者和正常对照的血样。AIM计划案例数量为350人。但是，我们还没有达到目标数字，所以我们一直在继续采集样本。而且该计划还没有得到分析。我们从我采集的血液样本中提取DNA。用聚合酶链式反应方法扩增雄激素受体的启动子区域，提取DNA片段。病例数量很少，毛乳头细胞的样本采集也没有进展。

We collected the blood sample, a patient of pattern of hair loss and normal control. The number of the aim plan cases is 350 people. However, we do not yet reach the aim numbers, so we have been continued sample collection. And the plan does not yet reach analysis. We extract DNA from the blood sample which I collected. And we amplified the promoter domain of the androgen receptor by PCR method and extract a DNA fragment afterwards. There is little number of the cases, and the sample collection of dermal papilla cells does not advance.
