Mice hemizygous for this transgene are viable. While males are fertile, transgenic females are unreliable breeders and mothers. Homozygotes are sterile. In both fetal and adult tissues, erythroid-specific expression of the transgene is observed. Transgenic mice have 120-150% greater mature body mass and increased bone mass. The donating investigator also reports transgenic mice have increased dermatological stiffness and toughness. Transgenic mice have a characteristic coat with few guard hairs compared to wildtype littermates. These mice may be useful in studies of bone formation and development, dermatology, and acromegaly. 

These transgenic mice harbor the human growth hormone gene driven by &Beta;-globin regulatory elements, and exhibit greater bone density and increased cortical bone thickness than controls.

Typically mice are recovered in 12-16 weeks. Contact Customer Service to place an order or for more information.
