Fig. 4.—
The spatiotemporal expression of the Cav α subunits subtype from Nematostella vectensis as determined by ISH. Gene expression is indicated by blue staining. The insets show the expression of Cav2a in nematocytes (stinging cells). In all pictures (not including insets), the oral end of all larvae is to the left. Abbreviations of developmental stages are: EP, early planula; MP, mid-planula; LP, late planula (tentacle buds are noticeable); and PP, primary polyp.
