Expression of ciliated bronchial epithelium 1 during human spermatogenesis

Our data strongly suggest an influence of CBE1 in ciliogenesis in spermatids due to the localization at the microtubules of the elongating spermatids, indicating a role in the intramanchette and/or intraflagellar transport mechanism. The absence of CBE1 in spermatozoa suggests that CBE1 is important for the spermatid development but not for the maintenance of mature spermatozoa as a component of the flagellum.
