(A) Testosterone and DHT supplementation had no effects on the number of EPC colonies in culture. (B) A similar trend was evident for the AUC of EPC colonies over the 15 days of culture. (C) Testosterone and DHT had no effect on adhesion of EPCs to a HUVEC monolayer. E2 served as a positive control. (D) E2, testosterone and DHT increased the generation of early AcLDL- and lectin-double-positive EPCs. *P≤0.05 compared with basal. T, testosterone.
