Gymnocladus dioicus K. is a large deciduous tree with unisexual flowers, which are good research materials for sexual differentiation. Researches from cytomorphology, cytohischemstry and analyses of special proteins on both male and female flowers in different developmental stages were systemly reported in this paper. The sex differentiation process of Kentucky coffeetree first undergo a vengetative stage, then a bisexual stage, finally unisexuality by means of the reduction or abortion of inappreciate sex organ primordial.

The density of AR of HFSC is consistent with the capability of differentiation of those cells. 3. Cells induced in vitro expressed EMA and Lipid droplets were observed by rathonum red staining, while those as control didn't, which confirmed that androgen can facilitate the differentiation of vibrissa follicle stem cells into sebocytes.

用免疫细胞化学检测到EMA在诱导后的细胞中的表达呈阳性，而在未经诱导处理的细胞中的表达呈阴性；用油红O染色检测到诱导后的细胞中有脂滴的形成，而在未经诱导的细胞中没有脂滴的形成；表明雄激素对毛囊干细胞向皮脂腺细胞定向分化具有促进作用。

To explore the possibility that the androgen may facilitate differentiation of hair follicle stem cells into sebocytes, we carried out experiments to test this hypothesis. The concrete steps to carry out this research were as follow: Firstly, observed the expression of AR and examined the expression of AR mRNA of rat vibrissa follicle stem cells in vivo in three defined phases of a hair follicle cycle, including anagen, catagen and telogen. Secondly, cultured HFSC deprived from vibrissa follicle bulge region in culture flasks and observed the expression of AR, ketertin 15 (K15), cluster of differentiation 34 (CD34) andβ1-integrin of those cells.

为了探索雄激素对毛囊干细胞定向分化为皮脂腺细胞的过程是否具有促进功能，我们进行了如下的实验来进行研究：第一步，检测了在毛囊周期的三个不同时期(生长期、退化期和静止期)中大鼠触须毛囊干细胞中AR、ARmRNA的表达以及检测原代培养的毛囊干细胞中AR的表达并探讨意义，为进一步研究打下基础。
