Delivery of Stem Cell-Rejuvenating Compounds via Subcutaneous Osmotic Pumps

Aging is widely regarded as an irreversible physiological process throughout the mammalian lifespan, characterized by functional tissue deterioration and increased disease incidence. One hallmark of mammalian aging is reduced tissue regeneration, primarily attributed to the declining function of tissue-specific stem cells. In recent years, various strategies aimed at rejuvenating stem cells through drug-delivery systems have been extensively explored. Here we describe a method for the long-term, controlled, systemic delivery of drugs using subcutaneous implantations of osmotic pumps.
