Primary cilia on porcine testicular somatic cells and their role in hedgehog signaling and tubular morphogenesis in vitro.

ABSTRACT: The primary cilium is a microtubule-based sensory organelle found on nearly all eukaryotic cells but little is understood about its function in the testis. We investigate the role of primary cilia on testis cells in vitro by inhibiting formation of the primary cilium with Ciliobrevin D, a cell-permeable, reversible chemical inhibitor of ATPase motor cytoplasmic dynein. We analyzed cultured cells for the presence of primary cilia and their involvement in hedgehog signaling. Primary cilia were present on 89.3 ± 2.3 % of untreated testicular somatic cells compared to 3.1 ± 2.5 % cells with primary cilia for Ciliobrevin D-treated cells. Protein levels of Gli-2 and Smoothened were lower on Western blots after suppression of cilia with Ciliobrevin D. The inhibitor did not affect centrosome local
