Electron microscopic images of white, HUMBLE and brown fat

Caption

Microscopic images of the various types of fat tissues developed in mice after transplantation. Top panels show the fat tissue's general morphology, and the bottom panels are the tissue sections stained with hUCP1 (red color), which is unique for brown fat cells. These images show that while the HUMBLE fat cells are morphologically similar to the white fat cells, they express the brown fat specific hUCP1 protein.
