[Cnidaria] identifying cells in Nematostella In-situ experiment.

[Dror Hilman]

Dear all,
I need some help to identify cells in Nematostella.
I recently performed whole-mount In-situ hybridization of Nematostella
adult (polyp).
The probe for the hybridization was the Nematostella ortholog for
neuronal - elav gene, a RNA binding protein, that used as neuronal
marker in mammals.
The color substrate is NBT-BCIP.
I have got a nice staining of the tentacles and the mouth (attached picture).
After the hybridization, I made cryo-section of the tissue, and I am
not sure about the identity of the cells that were stained.
Can you help me identify the cells - are they neurons?
