1 Sca-1(+)HSC induced aging by tert-butylhydroperoxide (t-BHP, final concentration of 100 mumol/L) for 6 h to establish the murine HSC aging model in vitro. tert-Butylhydroperoxide ataxin 1 Mus musculus
2 Sca-1(+)HSC induced aging by tert-butylhydroperoxide (t-BHP, final concentration of 100 mumol/L) for 6 h to establish the murine HSC aging model in vitro. tert-Butylhydroperoxide ataxin 1 Mus musculus
3 After 6 h cocultured with 100 mumol/L t-BHP, the ability of aging Sca-1(+) HSC to form mixed hematopoietic progenitor colony, self-renewal and multi-differentiation were decreased significantly. tert-Butylhydroperoxide ataxin 1 Mus musculus
4 The t-BHP can induce Sca-1(+) HSC senescence in vitro. tert-Butylhydroperoxide ataxin 1 Mus musculus
5 The signal transduction pathways of p16(INK4a)-retinoblastoma and P19(Arf)-Mdm2-P53-P21(Cip1/Waf1) may play key roles in the Sca-1(+) HSC senescence induced by t-BHP. tert-Butylhydroperoxide ataxin 1 Mus musculus
