Nuclear positivity in many cell types: white pulp B cells, megakaryocytes, many cells in red pulp. T cell nuclei around central arteriole of white pulp are negative.

This antibody recognises a sequence homologous to MEF2A  and MEF2C

Positive myoblast nuclei in developing skeletal muscle nuclei

Developing bone shows positve osteoblast nuclei ( and osteoclast?)

Some dentate gyrus neurones show positive nuclei.

Foetal stomach ( antrum ) shows strong basal positivity in the lumenal gland epithelium.

Mucosal overlying tonsil appears to have strong basal epithelial positivity. Occasionally this extends higher.
