摘要:
The good outcome of hematopoietic stem cell (HSC) transplantation is hampered by low doses of CD34(+) cell infusion. Transplanted HSCs undergo a replicative stress that causes accelerated senescence due to rapid telomere shortening. The expansion of human cord blood HSCs is instrumental in obtaining a large number of "good quality" cells, in terms of telomere length and telomerase activity compared to adult HSCs.
