Can you see this expansion in the cut block face? If not, then this
artifact may be due to over-expansion of the cut section on the waterbath.
To correct this problem, reduce the temperature of the waterbath and watch
the sections very carefully, picking them up just before they are fully
flattened (they will finish flattening on the slide).

Subject: Mouse Brain Processing
We have a problem with tissue processing we hope someone out there can
help us with. We are formalin-fixing, dehydrating, and wax-infiltrating
mouse brains in the standard manner for subsequent sectioning and staining.
Our problem is that the ventricles are greatly expanded. This morpholgical
distortion is critical, as we are doing quantitative immunohistochemistry
on the hypothalamus, and a third ventricle that looks like a football (or
worse) instead of a slit means the tissue lateral to the ventricle is
distorted and compressed. Any suggestions would be greatly appreciated.
