| Research Abstract |
Cdc42, 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 Cdc42 during limb development, we generated limb bud mesenchyme-specific inactivated Cdc42(Cdc42^<fl/fl>; Prx1-Cre) mice. Cdc42^<fl/fl>; Prx1-Cre mice demonstrated short limbs and body, abnormal calcification of the cranium, cleft palate, disruption of the xiphoid process, and syndactyly. Syndactyly in Cdc42^<fl/fl>; Prx1-Cre mice was caused by fusion of metacarpals and a failure of interdigital programmed cell death(ID-PCD). These results demonstrate that Cdc42 is essential for chondrogenesis and ID-PCD during limb development.
