MSC benefits are fantastic at replacing lost or damaged cells, however they are not bio-rejuvenation in the sense of turning back the clock with younger cells, unless one were to bank one's own younger cells?
If that is true, it would be, in a sense, an early SENS hack.
Very interesting. Will contact.
There has been some animal work that suggests transplantation may have that effect:

There is much research to be done, but the technology to transplant young bone marrow stem cells to one's older self exists today.
To be honest, that is part of my personal motivation. 'Autologous stem cell time travel' is low hanging fruit. We preserve the cells in multiple aliquots with the assumption that they might be used for multiple purposes, including expansion.
