Rejuvenation of aged blood stem cells is preclinical: RhoA inhibition with Rhosin (Nature Aging 2025) and CASIN are ex vivo mouse or human-cell work, and the one clinical-stage attempt, Rejenevie AR-100, was suspended (https://lifespan.io/road-maps/the-rejuvenation-roadmap/rejenevie-therapeutics-ar-100). Muscle satellite-cell restoration remains in reviews and animal models with no approved therapy (https://pmc.ncbi.nlm.nih.gov/articles/PMC5271918). The furthest-advanced human work is adjacent, not the goal: allogeneic MSC infusion (laromestrocel/Lomecel-B) missed its 180-day primary endpoint in a 148-participant phase 2b and reports a 9-month walk-distance gain in a later analysis (https://www.biospace.com/longeveron-s-cell-therapy-shows-mixed-results-in-aging-frailty-investors-respond-favorably), which is symptomatic benefit rather than a replenished endogenous stem cell pool; plasma exchange reduced multi-omic biological age by about 2.6 years with fading effects (Aging Cell 2025).
