Figure 1.

Fine structure of Tuft cells (TC) of mouse SMG. Shown is a transmission electron micrograph of TC in a mouse SMG striated duct (A). Note the bottle-like cell shape at the nucleus with narrow apical and basal portions consistent with TC morphology (B). There are numerous apical vesicles in the supranuclear cytoplasm (C). The yellow dotted line indicates a TC while the green and red arrows denote characteristic apical microvilli and tubulovesicular system, respectively. Scale bars represent 10 (A), 2 (B), and 2 (C) µm, respectively. Abbreviations: SMG, submandibular glands.
