Terminally Differentiated Epithelial Cells of the Thymic Medulla and Skin Express Nicotinic Acetylcholine Receptor Subunit α3

Figure 6

Immunolabeling for CGA. Both double- (eGFP⁺/CGA⁺, arrowhead) and single-labeled cells (eGFP⁺/CGA⁻, double-headed arrow; eGFP⁻/CGA⁺, arrow) can be observed. CGA-immunoreactive and eGFP-positive cells occur together in Hassall’s corpuscle-like structures (higher magnification in inset). Scale bar, 20 μm.
