• mice show cell-type specific ciliary abnormalities in chondrocytes, mouse embryonic fibroblasts (MEFs), and neocortical neurons, but not in epithelial cells or cerebellar granule cells
• decrease in the number of cells bearing primary cilium in the cerebral cortex, including the Tbr1-expressing cortical intermediate progenitors at E18.5
• chondrocytes show a 16.75% reduction in primary cilia length, although the change in prevalence of ciliation is not seen in E18.5 embryos
• MEFs exhibit unchanged primary cilia length but show a reduced ciliation frequency
• however, normal prevalence of ciliation is seen in Pax6-expressing granule cell precursors in the cerebellar anlage and in E-cadherin-expressing epithelial cells lining the dermal layer
