e-BAT, or engineered Brown Adipose Tissue (image) Dana-Farber Cancer Institute Share Print E-Mail Caption This is a microscope image of brown fat (e-BAT, or engineered Brown Adipose Tissue) created by adding a key control switch to skin cells of mice. Presence of green-stained objects (droplets of oil stored in the cell) confirms the skin cells have been converted to brown fat-producing cells. Blue objects are cell nuclei.
