Abstract
<p>Cells were treated as indicated. A. AKT, Chk2 and ERK1/2 were activated by E<sub>2</sub>-BSA and suppressed by puerarin. B. Western blot analysis of E<sub>2</sub>-BSA on phosphorylation in ESCs. Cells were treated with vehicle (DMSO) or E<sub>2</sub>-BSA (10<sup>−8</sup> mol/L) for 15 min. AKT, Chk2 and ERK1/2 were activated by E<sub>2</sub>-BSA. Expression was normalized to total ERK1/2.</p
