The natural course of aging, as well as the progression of several degenerative diseases, closely correlates with a loss of adult stem cell quantity and function.
Injecting muscle-derived stem cells harvested from young mice can recover the loss of stem cell proliferation and function observed in older mice, and in addition to anti-aging applications, mice with simulated Hutchinson-Gilford progeria syndrome significantly extended lifespan and improved health after stem cell injection.
This technology is a therapeutic method of administering autologous or allogenic stem cells isolated from younger donors in order to restore or rejuvenate adult stem cell function.
• Improved Performance of Regulatory T Cells in vivo.
Previous research demonstrated that CAR T cells with a more oxidative phenotype persisted longer in vivo persistence were more effective in targeting leukemia cells.
When applied to CAR T cells during the ex vivo expansion phase, the oxidative metabolism of these cells increased without negatively impacting cell growth.
