In answer to your question, yes. Supposing that you
could somehow rejuvenate the CD34+ positive stem cells
from your bone marrow, you would undoubtably extend
your life. Immortalizing them however is a tricky
proposition, because cellular immortalization without
tight regulation of growth is called cancer. So from a
systems point of view, rejuvenating your bone marrow
and thymus would add many years to your life. The
whole trick is figuring out HOW to do it without
causing leukemia.
