Cell morphology of AmSoxC expressing cells. (A) High magnification view of the ectoderm of in situ stained embryos (pear stage). (B) Double in situ hybridization of AmSoxC and Amlipase (planula stage). AmSoxC is stained black and Amlipase is red. (C) High magnification view of the surface of B. No overlapping staining is observed. Abbreviations: en = endoderm, ec = ectoderm.
