Mucosubstances in the colonic goblet cells of the ferret.

Mucosubstances in the colonic goblet cells of the ferret (Putorius [Mustela] furo) were studied histochemically. They contained predominantly sulphated mucosubstances in the proximal colon and only sulphated mucosubstances in the distal colon. The sulphated mucosubstances were of weakly acidic nature. Some deep cells and a few superficial cells in the proximal colon contained sialomucins which were sialidase-sensitive. Neutral mucosubstances were not found in the colon.
