Figure 6

Zebrafish ryr2b is expressed in the differentiating cardiac muscle. Expression of zebrafish nkx2.5, cmlc2, and ryr2b was examined using whole mount in situ hybridisation. Expression of nkx2.5 was observed in myocardial precursors from 11 hpf (3-somite stage) onwards, whereas cmlc2 and ryr2b were expressed in differentiating cardiac tissue from 14 hpf (10-somite stage) onwards. 11, 12 and 14 hpf embryos are orientated so that the anterior is to the top, whereas in 18, 24 and 48 hpf embryos anterior is to the left.
