| Outline of Final Research Achievements |
The bulbocavernosus (BC) is a sexually dimorphic muscle observed only in males. Androgen signaling plays a vital role in its development. To identify the mechanism of sexual dimorphism during BC development, AR mutation in the adjacent mesenchyme using Sall1 Cre driver mouse was performed, which resulted in defective BC formation. This study suggests that the nonmyocytic AR regulates the formation of myoblasts. Explant culture including Sall1 GFP positive cells responded to the addition of DHT. The culture system is expected to offer vital information for the functions of such mesenchyme in response to androgen.
