[Induction of prostatic buds in the urogenital sinus in Tfm mouse embyos without androgen receptors].

We have studied the prostatic bud induction in the urogenital sinus of androgen-receptor deficient mice, and found that epidermal growth factor (EGF), keratinocyte growth factor (KGF) as well as transforming growth factor-alpha (TGF-alpha) can provoke prostatic bud formation in the androgen-receptor deficient sinus cultured in the medium deprived of androgens.
