Proteins of K562 cells identified by Western blot. (A), Expressin of Akt, p-Akt proteins of K562 cells in SCG-S, CCG-S+MSCs and CG-S+MSCs+LY294002 groups. (B), Expressin of Bad, p-Bad proteins of K562 cells in SCG-S, CG-S+MSCs, CCG-S+MSCs+LY294002 groups. proteins were analyzed by Western blots with beta-actin as equally loading control (bottom). Independent experiments were repeated up to three times with the similar results.
