type I taste bud cell
type i taste bud cell
A densely staining taste receptor cell that contains many dense vacuoles in their apical regions which project into the apical space and bear microvilli. This cell type serves as a supporting cell by surrounding and isolating the other cell types from each other; secrete a dense amorphous material that surrounds the microvilli in the taste pore. This cell type expresses a glial glutumate transporter, GLAST.
