• immunostaining of primary MEFs revealed similar Cep120 signal intensity among the mother and daughter centrioles, indicating loss of the normal asymmetrical localization of Cep120 to daughter centrioles
• average ratio of Cep120 levels at daughter centrioles to those at mother centrioles is ~1 in mutant MEFs versus 1.4 in wild type MEFs
• mutant MEFs show higher Cep120 protein levels at mother centrioles (1:0.74 ratio), whereas Cep120 levels at daughter centrioles are similar to those in wild-type MEFs (~1:1 ratio)
• however, total Cep120 expression levels are not significantly altered relative to wild-type MEFs

• primary mouse embryonic fibroblasts (MEFs) derived from E10.5 mutant embryos lack cilia, unlike wild-type MEFs
