Fig. 6From: High-throughput transcriptome sequencing reveals the key stages of cardiovascular development in zebrafish embryosValidation of DEGs by qPCR. The expression of 18 hpf was set as 1, and the relative expression level of the other two stages (24 hpf and 42 hpf) was calculated for several genes. The asterisk indicates significantly different expression levels (*P < 0.05; **,*** and ****P < 0.01)Back to article page
