Significant differences between the SOX4 transgenic fish and wild-type are indicated (*P<0.05; **P<0.01; ***P<0.001) by Mann–Whitney U-test.

Significant difference of groups between the SOX4 transgenic fish and wild-type are indicated (^#P<0.001) by one-way analysis of variance (ANOVA).

^aA total number of 300 cells per zebrafish was counted to classify the distribution and subtypes of these hematopoietic cells.
