The aim of this study was to determine whether human erythropoietin ( rhEPO ) reduces the astrocytic swelling created by oxygen - glucose deprivation followed by reoxygenation ( OGD / Reox ) in vitro and whether this effect can be mediated through the modulation of aquaporin4 ( AQP4 ) expression in the plasma membrane ( PM ) and phosphorylation of the mitogen - activated protein kinase pathway ( MAPK ) pathway .
