Brief Communication: Histological Assessment of Nonhuman Primate Brown Adipose Tissue Highlights the Importance of Sympathetic Innervation

Figure 2

Significant histological features and BAT density correlates of tyrosine hydroxylase density. Panel (a) depicts the positive correlation between uncoupling protein 1 (UCP1) and tyrosine hydroxylase (TH) ( value = 0.02, r = 0.46, n = 26). Panel (b) depicts the positive correlation between cytochrome c oxidase subunit 4 (COX IV) and TH ( value = 0.006, r = 0.52, n = 26). Panel (c) depicts the positive correlation between cluster of differentiation 31 (CD31) and TH ( value = 0.007, r = 0.52, n = 24). Panel (d) depicts the positive correlation between brown adipose tissue (BAT) cell density and TH (p = 0.02, r = 0.48, n = 24).
