What do mucous glands look like when stained with H&E?
The mucinogen doesn't take up H&E very well and the nuclei are flattened and pushed basally.
31
Kartenlink
0
How do serous glands look when stained with H&E?
They stain pink because of all of the eosinophillic enzymes.  The nuclei are round and basal.
