Exosomes are small membrane-wrapped packages of molecules that play a crucial role in cell-to-cell communication. While the taxonomy of extracellular vesicles is based on size, exosomes exhibit subtle differences based on cell type and environment. Stem cell therapies have evolved into exosome therapies due to ease of harvesting, storage, and delivery. Researchers are exploring exosomes harvested from urine-derived stem cells, which have shown promise in delaying aging through the transfer of specific proteins. This innovative approach holds great potential in anti-aging therapies.
