Histological differences in the liver

The images below show Masson's trichrome staining of the liver from mice fed either a normal chow or a high fat diet. The dark red shows nuclear staining and the lighter red/pink shows keratin and cytoplasmic staining. The blue shows the staining of collagen. There are a number of signature characteristics that allow you to histologically identify the liver obtained from animals fed either chow or a high fat diet.

Drag and drop the appropriate label for each of the images:

Chow-fed (control)

High fat-fed (obese)

Congratulations! You've correctly identified the signature characteristics of the livers.
