Figure 7From: Long-term culture and significant expansion of human Sertoli cells whilst maintaining stable global phenotype and AKT and SMAD1/5 activation Expression of PCNA, phos-AKT and phos-SMAD1/5 in human Sertoli cells after culture for 2Â months. Western blots displayed the expression of PCNA, phos-AKT, and phos-SMAD1/5 in human Sertoli cells at P1, P5, P10. ACTB served as the control of loading proteins.Back to article page
