The demonstration of cilia in canine macula densa cells This investigation was supported by funds from Faculty Research Grant 360208, Kidney Foundation of Michigan and NIH Grant 082020.

Abstract

Although the presence of cilia in mammalian epithelia is common, the finding of cilia in the macula densa cell of the kidney has never been reported. In this paper are reported electron microscopic observations of cilia in canine macula densa cells. The cilia observed have the classic 9+2 configuration. The centriole, basal body, foot process, ciliary rootlet and the substructure of the latter also were observed.
