Brown adipose connective tissue
(20x objective lens)
At this magnification, the most prominent feature of brown
adipose cells is the highly vesiculated cytoplasm.
The unstained spaces of variable size mark
the location of the multiple fat droplets that characterize these cells.
The lipids are dissolved during dehydration, leaving the empty spaces, which do
not stain. The vesicles are surrounded by eosinophilic cytoplasm.
