Figure 6From: Long-term culture and significant expansion of human Sertoli cells whilst maintaining stable global phenotype and AKT and SMAD1/5 activation Protein expression of GDNF, SCF and BMP4 in human Sertoli cells at different passages. (A-D) Western blots showed the expression of GDNF, SCF and BMP4 in human Sertoli cells at P1, P5 and P10. ACTB was used as the control of loading proteins.Back to article page
