Fig. 1
Endoderm-specific expression of G?13 rescues defects in migration of the endoderm and myocardial cells caused by global G?13 depletion. (A-A?) Epifluorescence images of anterior endoderm and myocardial cells in embryos indicated. (B-E) Epifluorescence images of anterior endoderm of control and gna13a/b MO-injected embryos indicated. (F) Frequencies of cardia bifida and tail blistering in embryos indicated (same as in B-E) at 2?dpf. Dorso-anterior view, with anterior up; yellow dots, cardiomyocytes; white lines (equivalent length), width of the anterior endodermal sheet. *P<0.001, #P=0.25. Data are meanąs.e.m.
