• homozygous null MEFs displayed a marked inhibition of migration in a scratch-wound repair assay, covering only 20-30% of the wound area compared to complete wound closure in wildtype, however homozygous null mice were viable and reached adulthood without any obvious phenotypes
• migrating homozygous null MEFs exhibited abnormal lamellipodia production with decreased levels and activation of FAK, p130Cas, and Rac1
