Phenotypic analysis of the embryos injected with three crRNAs, tracrRNA and Cas9 protein.
(A) An uninjected embryo. (B) Tg(cmlc2:EGFP)-derived embryos injected with tracrRNA (100 pg), spns2-crRNA2 (25 pg), s1pr2-crRNA1 (25 pg) s1pr2-crRNA2 (25 pg) and Cas9 protein (400 pg). (C) Tg(cmlc2:EGFP)-derived embryos injected with spns2-gRNA1 (25 pg), s1pr2-gRNA1 (25 pg), s1pr2-gRNA2 (25 pg) and Cas9 protein (400 pg). Cardia bifida was observed in the embryo injected with multiple crRNAs, tracrRNA and Cas9 protein, whereas a normal single heart was observed in an uninjected embryo and the embryo injected with multiple gRNAs and Cas9 protein. (A-C) Ventral view with anterior at the top. White arrowheads indicate the position of the developing heart.
