Telomere shortening in hematopoietic stem cell transplantation: A potential mechanism for late graft failure?
1 Nov 2002
Abstract excerpt
Telomeres serve to maintain the structural integrity of chromosomes, yet each somatic cell division is associated with a decrease in telomere length. The cumulative decrease in telomere length can impose an upper limit for the number of cell divisions that can occur before a cell senesces. When studied in vitro with fibroblasts, this limit is referred to as the Hayflick limit and usually occurs after 40 to 80...
