Number of UCP1-positive multilocular adipocytes at 28°C and after cold exposure. (A) C57BL/6J and (B) Sv129 mice: anterior subcutaneous depot (composed of superficial cervical, deep cervical, interscapular, axillo-thoracic, and subscapular portions); posterior subcutaneous depot (composed of inguinal-dorsolumbar and gluteal portions); mediastinal depot, mesenteric depot, retroperitoneal depot, and abdominopelvic depot (composed of interrenal, periovarian, perivesical, parametrial, and periovarian portions). The data on C57BL/6J mice are the same presented in supplementary Table II. Sv129 data were obtained from a previous work (26). Mean ± SEM. *P < 0.05, **P < 0.01.
