If blood loss necessitates immediate cell division to replace lost cells, does the increase in cell division correlate to shortening of telomeres? Does it further cause the Hayflick Limit to be reached sooner? Does blood loss accelerate apoptosis?
Nope, nope, and nope. A cursory glance over any page on hematopoesis will reveal that blood cells are replenished from HSC, hematopoetic stem cells, which are self-renewing stem cells. Telomerase is activated in stem cells.
