Figure 6

Longitudinal and transverse sections of chondrocyte cilia obtained by transmission electron microscopy. The longitudinal section and red lines (left) indicate the approximate position of transverse sections. Transverse sections of cilia are from wild-type (+/+) and Evc mutant (-/-) chondrocytes cells. In both genotypes, disorganized doublets were found in the distal region (red arrow heads) and the champagne glass structures were found in the proximal region (green arrow heads). Nine triplet microtubules and spike structures (blue arrow heads) could be identified in transverse sections of basal body. Scale bar 100 nm.
