ABSTRACT
Objective To explore the influence of cerebral hemorrhage stress on endothelial progenitor cells(EPCs) proliferation and senescence. Methods Mononuclear cells from peripheral blood of patients with cerebral hemorrhage (CH group) and patients with the same underling diseases (control group) as the front were isolated and induced to EPCs. Proliferation, numbers of colonies and cells, senescence of EPCs were checked and compared between the two groups. Results Compared with control group, proliferation (0.270 ± 0. 074 vs 0. 185 ±0.050, t=3.802) ,numbers of colonies( (5. l0 ±0.79) cell/HPF vs ( 1.90 ±0.41 ) cell/HPF, t= 14.407) and cells( (75.15 ± 10.48) cell/HPF vs(57.10 ± 9.28 ) cell/HPF, t = 5. 157 ) of EPCs in CH group on the stress of cerebral hemorrhage were increased significantly (P < 0.01 ), but senescence of EPCs ( (45.54 ± 5.74 ) cells/100 cells vs ( 46.86 ± 5.06 ) cells/100 cells, t = 0. 686 ) in two groups were not different (P > 0.05 ). Conclusion Cerebral hemorrhage stress can increase proliferation of EPCs,but can not change the senescence destiny of EPCs.
