Figure 1From: Neuroprotective activity of a new erythropoietin formulation with increased penetration in the central nervous systemProtective effect of rhEPO derivatives on differentiated PC-12 cells upon induction of apoptosis by NGF and serum withdrawal. rhEPO, rhNEPO and desialylated rhEPO (rhAEPO) were added to the culture 24 h prior to induction of cell death. Apoptosis was measured by TUNEL technique.Back to article page
