Moderate positivity in epidermal cells. Strong positivity in hair papilla.

Hypodermal  muscle cells also appear positive.

Interesting tooth positivity.

Note that what appear to be osteoclasts ( or osteoblasts) are also positive ( see adjacent developing  jaw bone.

Mucosal  epithelium is also positive ( lower left and upper right of the image).

Strongest positivity is seen in the hair papillae, it seems

Comments on my CD44 positivity are welcomed/appreciated.

Intense positivity in developing filiform papillae of tongue (lower) and also in the membranes of suprabasal cells of the hard palate epithelium ( upper epithelium)

Nests of cells are intensely positive.

Also, in this specimen, rbcs are positive.

An intense positivity in a subset of ear canal lining cells.

A variable megakaryocyte cytoplasmic positivity.

Intense positivity in a subset of airway lining cells.

A moderate background positivity?

If so, dilute further.

Excellent, even positivity throughout enterocyte cytoplasm.
