We argue that age-related changes in HSCs and in the hematopoietic system may not
entirely be due to a degenerative aging process, but are the result of developmental and
stem cell-protective mechanisms aimed at maximizing fitness during reproductive life. These
mechanisms may be disadvantageous later in life as damaged HSCs accumulate and
establishment of responses to neoantigens becomes compromised because of the reduced
generation of naive T and B cells.
