Figure 1: Expression of syndecan-4 in testicular germ cell tumours and cell lines. (a) Indicative RT-PCR analyses of syndecan-4 compared to reference gene GAPDH in two control normal testicular tissues (lanes 1 and 2), three NSGCTs (lanes 3, 4, and 5), and in three seminomas (lanes 6, 7 and 8). (b) Semiquantitative analysis of syndecan-4 expression in normal testicular tissues (), NSGCTs (), and seminomas (). (c) RT-PCR analyses of syndecan-4 compared to GAPDH in testicular GCT cell lines. (d) Semiquantitative analysis of syndecan-4 in TGCT cell lines. The data are presented as the median ± SE and analysed using two-tailed Student’s -test ().
