Propagation of Ca2+ responses among taste bud cells

Abstract

Biological chemical sensors, taste buds, consist of ∼ 40 cells each in mice. These taste bud cells are suggested to form cell networks within taste buds. Here we show that the elevation of Ca²⁺ in a taste bud cell is propagated to another cell. These results agree with the hypothesis and will be applied to the manufacturing of the network of chemical sensors.
