Much like giving blood, the bone marrow reconstitutes its self relatively quickly. The reason there's an advantage in re-introducing them later in life is that as we age we have a less circulating stem cells and the ones that we do have become less and less effective at doing their jobs. This is thought to be a major cause of aging. You can learn more at our website. Cheers
