Primary cilia (PC) extend from the basal cell main body. Confocal imaging performed in the caput epididymidis of Arl13b-Cetn2 dTg adult mice showed a basal cell with a characteristic axiopodia (Axp.) extending from its main cell body. Arl13b-positive PC extend from centrin2-positive centrioles located at the base of the axiopodia. No PC extension was found within the axiopodial extension in the caput, corpus or cauda epididymidis. This figure is representative of acquisitions performed on n = 10 mice. Bc.: basal cell; Ep.: epithelium; Lu.: lumen; Mc.: myoid cells. Scale bar: 10 μm.
