Abstract
Vesicles originated in the Golgi complex are found in the supranuclear areas of the taste bud cells in various concentrations, and they aggregate in a considerable number just beneath the apical surface membrane of the differentiating cells where microvilli are destined to form. This evidence adds further weights to a hypothesis that specialization of the cell surface arises partly by a mediation of the Golgi-derived vesicles. In addition, the present cytochemistry also indicates that these Golgiderived vesicles are preformed units of the plasma membrane which carry surface coat material assembled in the Golgi complex to the apical surface membrane.
