On the cover: Relationships between adipocytes, vasculature, and LYVE-1+ macrophage distribution. Whole-mounted tip region of epididymal adipose tissue from 8-week-old mice is visualized by fluorescent immunostainings of perilipin (for adipocytes, red), PECAM-1 (for blood vasculature, green) and LYVE-1 (for macrophages, blue), and merged. A characteristic dense vascular network is present in the tip region, where large numbers of LYVE-1+ macrophages are present. See related article, page e47.
