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

我们收集了一名脱发型患者和正常对照的血液样本。目标计划的人数为350人。然而，我们还没有达到目标数字，所以我们一直在继续收集样本。该计划尚未达到分析。我们从我收集的血样中提取DNA。用PCR方法扩增了雄激素受体的启动子区，并提取了DNA片段。毛乳头细胞的标本采集也没有进展。

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.
