Immunohistochemistry analyses were performed as described previously 17 (link). For apoptotic cells analysis, paraffin-embedded tissue sections were stained with anti-Perilipin (Abcam, Cat. No. ab-61682) and cleaved caspase-3 (Cell Signaling Technology, Cat No. 9664) antibodies. Images were captured using a NanoZoomer slide scanner system with NanoZoomer Digital Pathology software (Hamamatsu) or confocal fluorescence microscopy. Microscopic images were analyzed using ImageJ software.
