Figure 5.

Comparative results from flow cytometry analysis of EGFP-expressing cultured Sertoli cells in vitro transfected with the pGtoR or pRed. The graph shows the mean (Mean ± SE) of green fluorescence intensity in cells transfected in vitro with the pRed or pGtoR, determined by flow cytometry at 3, 5 and 7 days after transfection. Asterisk shows statistically significant differences as measured by p < 0.05.
