Change in expression of EPO in cultured astrocytes during hypoxia alone (hypoxia) or oxygen/glucose deprivation (OGD). a Time course of the change in EPO mRNA expression. Data are the mean ± SEM (n=3 in each group). b EPO protein concentrations were measured in astrocyte-conditioned medium 24 h after hypoxia and OGD. Data are the mean ± SEM (n =6 in each group). ^‡P < 0.05 compared with the control group. ^*P < 0.05 compared with the No glucose group. ^#P < 0.05 compared with the Hypoxia group
