Doctors are using a procedure for harvesting and growing stem cells from a person’s own body fat, and then injecting them back into the body. Will a combination of nutritional supplements actually accomplish almost the same thing, without the invasive manipulation?

You have seen intuitively, that the transplant procedure is more a gimmick than a requisite for helping the body restore itself. While that approach can speed the appearance of benefit, it is not in any way essential to accomplishing the objective sought in doing a body-wide repair via stem cell activation. This puts the body in more a growth mode to favor strengthening and repair along with growth, so important for the youth phase of development. When that is no longer needed to grow the body to its eventual adult size, those hormonal triggers can become quiescent and not be needed, but the processes of cellular replacement and restoration continue to be of value because the tissues and organs need to be maintained for the duration. As you know, there is a steady turnover of all that is in the body, requiring replacement with new cells. This is, in part, a communication from the stem cell compartment to trigger cell replication in addition to providing a source of new cells. This has not been fully worked out by science as yet, in showing that stem cells represent a one-two punch, so to speak, by bringing in fresh sources of bodily cells to replace what is lost through degeneration, but also to stimulate existing tissue and cellular makeup to undergo a restoration and repair so not all must be replaced by fresh cells from outside the tissue. That will not be needed, but the stem cells are the delivery system for such signaling and as such, causing a recruitment through an awakening and migration of the cells to areas needed will be a necessary part of the process.
