(a) Control and Cc2d2a−/− E10.5 mouse embryo littermates. (b) Control and Cc2d2a−/− E9.5 ventral neural tube stained for Arl13b (red) and DNA (DAPI, blue). (c) Control and Cc2d2a−/− E9.5 perineural mesenchyme stained for Arl13b (red) and DNA (DAPI, blue). (d)
Cc2d2a−/− primary MEFs generate cilia, marked by AcTub (green), with associated basal bodies, marked by γ-tubulin (red). (e) Hematoxylin and eosin staining of E18.5 kidney sections from control and Tmem67−/− embryos. Kidney cysts are visible in the mutant (arrows). (f) Control and Tmem67−/− E18.5 embryonic kidney tubules stained for AcTub (green), Arl13b (red) and DNA (DAPI, blue). Cilia are less abundant in Tmem67−/− tubules, but possess Arl13b. (g)
Tmem67−/− primary MEFs generate cilia, as stained for AcTub (green), γ-tubulin (red), and DNA (DAPI, blue). (h)
Tctn1 is epistatic to Tmem67. At E14.5, Tmem67−/− mice are indistinguishable from wild type, and Tctn1−/−
Tmem67−/− double mutant mice are indistinguishable from Tctn1−/− mice. Scale bars 10μm.
