Fig. 3.

Expression of four vasa paralogs in Mnemiopsis embryos at 10–12 hpf. Views for each gene are shown in aboral (left column) and lateral (right column) orientation. MlVasa1 was expressed in the ectoderm between the comb plates and the sagittal axis as well as in the tentacle bubs and pharynx. MlVasa3 was expressed in the developing comb plates. MlVasa4 also showed expression in the ectoderm between the comb rows and the tentacle bulbs. MlVasa5 expression was detected aboral ectoderm in a region corresponding to the apical organ floor and the polar fields. Expression for MlVasa2 was not determined
