FIG. 1.

Immunohistochemical localization of vascular and stem cell markers in the adipose tissue. Human adipose tissues were examined by immnuohistochemistry for the expression of α-SMA (A), CD31 (B), CD34 (C), and SSEA1 (D). Positively stained structures are marked with arrows. Control specimen stained with HE (without antibody) is shown in (E), and two areas of which (a and b) are enlarged and displayed in (F). The small artery, the arteriole, and the capillary are approximately 70, 25, and 10 μm in diameter, respectively.
