Elevation of stromal cell-derived factor 1 and C-X-C chemokine receptor type 4 in white matter damage treatment with recombinant human erythropoietin and human umbilical cord mesenchymal stem cells in a rat model of preterm birth.

CONCLUSIONS: The rhEPO and hUC-MSCs intervention reduced injury area, increased body weight at P7, and improved neurobehavioral scores at P28. Furthermore, their combined use proved even more beneficial. SDF-1 levels in the rhEPO group were higher than those in the other groups and highest in the hUC-MSCs + rhEPO group (all p < .01). SDF-1 levels in the hUC-MSCs + rhEPO and rhEPO groups were increased at P5 and reached a peak at P7. CXCR-4 levels in the hUC-MSCs group were higher than those in the other groups and highest in the hUC-MSCs + rhEPO group (all p < .01). CXCR-4 levels were also increased at P5 and highest at P14. SIGNIFICANCE: hUC-MSCs + rhEPO might reduce nerve cell damage and improve neurobehavioral development, in connection with increased SDF-1 and CXCR-4 expression, in premature rats with WMD due to hypoxic-ischemic injury.
