Massive increase in microglia numbers in lesioned brain ( I note the positive ? macrophages? in the pia mater )

Strong positivity is seen in progenitor olfactory interneurons, maturing in the svz of the lateral ventricle and also in microglia.

Specific? Non-specific?

Positivity is  strong in the cytoplasm of the progenitor olfactory interneurones from the RMS.
