To determine whether mammalian Müllerian-inhibiting substance (MIS) is active in birds, Müllerian ducts from 7- to 8-day-old male or female chick embryos were cultured in the presence of human recombinant MIS at concentrations between 2.5 and 12.5 micrograms/ml. None of 20 ducts regressed at any concentration. In contrast, at concentrations of 2.5-5 micrograms/ml, all 12 Müllerian ducts from 13-day-old male mouse embryos and 13 out of 14 female ducts were inhibited to varying degrees. It is concluded that avian Müllerian ducts are unresponsive to mammalian MIS. There may be a difference in structure between the MIS of birds and mammals, or the signal-transduction system may be different.

D009095	Mullerian Ducts	A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of testicular ANTI-MULLERIAN HORMONE. In the absence of anti-mullerian hormone, mullerian ducts give rise to the female reproductive tract, including the OVIDUCTS; UTERUS; CERVIX; and VAGINA.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
