We also observed the expression of transporters on the cuticular plate, which has not been previously reported and is consistent with our observation of 2-NBDG uptake by OHCs through the cuticular plate using live-cell imaging (data not shown).
Our examination of the distribution of GLUT isoforms using specific antibodies identified the expression of glucose transporters on the cuticular plate, in accordance with our live-cell imaging results showing glucose uptake at this location (data not shown).
Textbooks, she said, describe the roots of the stereocilia ending in the cuticular plate
. But the new pictures showed that the roots continue through, make a sharp 110-degree angle, and extend all the way to the membrane at the opposite side of the cell, where they connect with the striated organelle.
Surviving HCs are characterized by the presence of stereocilia and cuticular plates
. The HCs were characterized as damaged (i.e., missing) if no stereocilia and cuticular plate
Another fraction was apparently tightly bound within the cuticular plate
. In hair bundles, myosin VI was associated with basal tapers of a fraction of stereocilia (only 10%-25%).
These hardened cuticular plates
, acting as deflectors, are located just outside the opening of the reaction chamber, and give directional control to the discharge by changing their angle of deflection.
In insects which feed on solid food, the inner wall of the proventriculus becomes armed with strong cuticular plates
or teeth which grind the food (Snodgrass 1935).
