Expression of Erythropoietin-receptor. (A) Western blot analysis of EpoR expression levels of hNPC cell lysates at 20% O2 (black bars) and 3% O2 (white bars) in proliferating and 3 days differentiating cells. (B) Quantification of the western blot data. No significant change of the signal intensity was detected; neither between proliferating and differentiating cells nor in EPO-treated cells (mean ± SEM).
