Co-culture with EPCs and NPCs activated the PI3K/Akt signal pathway on H/R-injured ECs. a, VEGFR2 expression was significantly upregulated in H/R-injured ECs co-cultured with NPCs or the combination of EPCs and NPCs. b the protein expression ratio of p-Flk1/VEGFR2 was significantly increased in H/R-injured ECs co-cultured with EPCs or NPCs, with a higher ratio in ECs co-cultured with the combination of EPCs and NPCs. c the protein expression ratio of p-Akt/Akt was increased in H/R-injured ECs co-cultured with EPCs and NPCs, and this effect was blocked or reduced when ECs were pre-treated with PI3K inhibitor LY294002 or VEGFR2 inhibitor SU1498 or TrkB inhibitor K252a. *p < 0.05, vs. Normoxia; #p < 0.05, vs. vehicle.
