Mouse Thyroid Gland Changes in Aging: Implication of Galectin-3 and Sphingomyelinase

Figure 5

Fluorescence immunostaining of neutral sphingomyelinase (nSMase), by using anti-nSMase antibody in thyroid tissues of young and old mice. The high level of fluorescence is found in the thyrocytes and colloid of young animals. With aging, the fluorescence localization increases in thyrocytes and reduces in colloid. 20x magnification.
