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

Figure 4

Immunohistochemical expression of galectin-3. Strong staining is seen in the majority of follicles and in interfollicular spaces of old mice, as shown by arrows. The positivity of staining was measured as the percentage of total area (follicles and interfollicular spaces). Data represent the mean ± S.D. of three independent experiments performed in duplicate. 40x magnification. Significance, , versus young sample.
