Effect of sox9b-null mutation and TCDD treatment on pericardial area, heart length, and blood flow
Control, homozygous sox9bb971 deletion mutants, and TCDD-treated wild-type fish were obtained by spawning and TCDD exposure as described in Materials and Methods. Pericardial area, heart length, and blood flow rate were measured using videomicroscopy as described in Materials and Methods. Results are presented as the mean ± S.E.M.
