catagen

The DPC distributed in two different types during catagen.

体外培养的人发毛囊在培养中后期进入退化期后，毛乳头细胞存在两种分布类型；

Conclusion hair growth lotion can promote the growth of hair follicle by inhibiting the appearance of catagen.

结论：生发液能够延缓器官培养毛囊的退化期出现而延长生长期，促进毛囊长度的增长。

The morphology study showed that catagen/ telogen stages occurred in the hair follicles in the control group, while the hair follicles in the experimental group were still maintaining in anagen stages.

毛球形态观察，对照组毛囊出现退行性变化，而中药组毛囊仍维持生长期毛囊形态。

The growth of human HF cultured in vitro varied with the different cultural media, those in DMEM supplemented with 10% calf serum tended to transform into catagen earlier.

人发游离毛囊体外培养中，培养基构成对毛囊的生长有直接影响。含小牛血清的DMEM培养基中生长的毛囊易于进入退化期；

On the basis of HF development we could divide HF cycle into four stages, i.e. anagen, catagen, telogen and a putative active exogen.

根据毛囊的发育和生长可将毛囊循环周期分为四个阶段，即生长期（anagen）、退化期（catagen）、静止期（telogen）和一个推测的活跃脱毛期（exogen）[17,36]。
