The expression of the S. sq VEGFR gene in the H. roretzi tissues is correlated with the existence of circulatory system. (a) RT-PCR analysis of S. sq VEGFR gene expression in the different H. roretzi tissues. Upper panel: PCR was performed using a S. sq VEGFR-specific primer set and reverse-transcribed cDNA from the total RNA of each tissue as the template. Lower panel: PCR was preformed using the H. roretzi β-actin-specific primer set and reverse-transcribed cDNA from total RNA of each tissue as the template (positive control); (b) Anatomical scheme of H. roretzi.
