description

Telomeres cap chromosomal ends and are shortened throughout a lifetime. Additional telomere erosion has been documented during conventional chemotherapy or hematopoietic stem cell transplantation. Previous studies of stem cell transplantation reported variable amounts of telomere shortening with inconsistent results regarding the persistence of telomere shortening. Here we have prospectively studied telomere length and proliferation kinetics of hematopoietic cells in aggressive non-Hodgkin lymphoma patients who underwent a four-course high-dose chemotherapy protocol combined with triple autologous stem cell transplantation. We observed sustained telomere shortening in hematopoietic cells after triple stem cell transplantation with prolonged stem cell replication during the first year after stem cell transplantation.
