Fig 1 Schematic of erythropoietin (EPO) receptor induction. Schematic depicting ischemic effects on tissue with EPO receptor expression preceding endogenous EPO production and without exogenous administration, ongoing neuronal loss may ensue. (BCL-2 = B-cell lymphoma 2; STAT3 = signal transducer and activator of transcription 3.)

Fig 3 Ischemia-reperfusion (I/R) induction of (A) beta-common receptor (βcR) and (B) phosphorylated signal transducer and activator of transcription 3 (pSTAT3). The βcR receptor subunit expression and STAT3 activation are increased in all ischemic groups compared with shams. ∗ signifies p <0.05. (EPO = erythropoietin; GAPDH = glyceraldehyde 3-phosphate dehydrogenase.)

Fig 4 The beta-common receptor (βcR) subunit induction by oxygen-glucose deprivation (OGD). The OGD induces βcR expression in neurons (5.4 ± 1.35 vs 2.4 ± 0.33, p = 0.03) and astrocytes (4.2 ± 0.35 vs 2.5 ± 0.3, p = 0.01). ∗ signifies p <0.05.
