Abstract:
Objective To investigate the cytokine spectrum and henlatopoiesis-supportive function of umbilical cord derived mesdnchymal stem cells(UC-MSC),and compare with those of normal adult bone marrow derived mesenchymal stem cells(BM-MSC).Methods The mRNA of cytokine production of UC-MSC and BM-MSC were determined by reverse transcriptasc polymerase chain reaction(RT-PCR)analysis.To evaluate hematopoiesis supporting activity,cord blood(CB)CD+34 cells were co-cultured with UC-MSC or BM-MSC.Colony-forming cells(CFC)were determined after 5 weeks of culture.Results RT-PCR assay showed that UC-MSC had a cytokine spectrum very similar to that of BM-MSC.including expression of the mRNA ofstem cell factor,leukemia inhibitor factor,macrophage colony stimulating factor,Flt3-ligand,interleukin-6,vascular endothelial growth factor and stromal derived factor-1.but UC-MCS additionally expressed mRNA of granulocyte macrophage and granulocyte colony-stimulating factors.After co-culture with CD+34 cord blood cells for 5 weeks,no significant difference in CFC was observed between the CD+34 cells/UC-MSC and CD+34 cells/BM-MSC co-cultures (P＞0.05). Conclusion The cytokine spectrum and hematopoiesis-supponive function of UC-MSC ale similar with that of BM-MSC.
