Description

There is a greater frequency of microsatellite instability in hematopoietic stem cells and colony-forming cell-derived clones from old human donors (aged > 45 years), when compared with younger individuals (aged < 45 years). This is also associated with the loss of MutL homologue 1 (MLH1) protein expression, one of the genes belonging to the mismatch repair pathway (responsible for replication fidelity).
