Fig. 3. DiI injection in the posterior SHF of embryos at the 4- to 6-somite stage. (A,B) DiI injection (at sites arrowed) in the right (A) and left (B) pSHF of mouse embryos at the 4-somite stage. The squares indicate the pSHF region (see also Fig. 1). (A',B') DiI labelling (red) in the same embryos after 40 hours of culture, focussing on the heart (dorsal view). (C) DiI (red) injection in the left side and DiR (blue) injection in the right side of an embryo at the 7-somite stage. (C') The same embryo after 40 hours of culture (dorsal view). AVC, atrioventricular canal; LCA, left common atrium; OFT, outflow tract; RCA, right common atrium; RV, right ventricle.
