Estradiol (Synonyms: 雌二醇; β-Estradiol; E2; 17β-Estradiol; 17β-Oestradiol)
Estradiol (β-Estradiol) 是一種類固醇激素和主要的女性性激素。Estradiol 可上調(diào)人子宮內(nèi)膜干細胞 (hEnSCs) 神經(jīng)標志物的表達并促進其神經(jīng)分化。Estradiol 可用于癌癥、神經(jīng)退行性疾病和神經(jīng)組織工程的相關(guān)研究。
生物活性
Estradiol (β-Estradiol) is a steroid hormone and the major female sex hormone. Estradiol can up-regulate the expression of neural markers of human endometrial stem cells (hEnSCs) and promote their neural differentiation. Estradiol can be used for the research of cancers, neurodegenerative diseases and neural tissue engineering[1][2].
