Peritoneal squamous epithelium is positive.

Particularly strong positivity is seen in these cells covering an artery.

Note the punctate positivity in peritoneal lining cells?

Comments welcomed.

Is this a useful B-cell or Plasma cell marker?

Diagnostic value?

Be grateful for explanation as epidermal/mucosal epithelial cells are also positive ( membraneous: seems to stop at end of spinosal cell layer).

Podocytes are positive for Nestin

Also, one can see primary processes wrapping around capillaries.

Why are adult podocytes positive for Nestin?

Positive migrating olfactory bulb progenitor interneurones.

Yes….endothelial cells are also positive.
