Research Abstract |
Rac1, a member of the Rho subfamily of small GTPases, is known to be a regulator of multiple cellular functions, including cytoskeletal organization, cell migration, proliferation, and apoptosis. To investigate the physiological function of Rac1 during bone and cartilage formation, we generated tissue-specific inactivated Rac1(Rac1fl/fl ; Prx1-Cre) mice. Rac1 conditional knockout mice demonstrated short limbs and incomplete fusions of the cranium. Our results infer that short limb was caused by abnormal endochondral ossification and incomplete fusion of the cranium was due to enhanced mineralization.
