Further characterization of the PW peptide family that inhibits neuron differentiation in Hydra - Discover Developmental Biology

Immunohistochemical staining of a normal and an epithelial Hydra with an anti-Hym-33H antiserum. For both hydra, a signal was detected in ectodermal epithelial cells throughout the body with the exception of the basal disk. a Head region and b foot region of a normal hydra. c Enlargement of stained ectodermal epithelial cells in a part of the body column of a normal hydra. d Head region and e foot region of an epithelial hydra. f Enlargement of stained ectodermal epithelial cells in a part of the body column of an epithelial hydra. g Differential interference contrast image of a part of the body column. Ectodermal (Ect) and endodermal (End) epithelial layers separated by the mesoglea (arrowhead). h Confocal image of (g)
