Core Viewpoint - The article discusses the potential of antler blastema progenitor cells (ABPC) and their extracellular vesicles (EV ABPC) in promoting healthy aging and reversing age-related conditions in mice and macaques, highlighting their unique regenerative capabilities and implications for anti-aging therapies [4][10][12]. Group 1: Research Findings - A recent study published in Nature Aging demonstrates that EV ABPC can reverse bone loss and mitigate aging-related phenotypes in animal models [3][4]. - The study identifies unique factors within EV ABPC that alleviate aging symptoms, such as improving bone mineral density and enhancing cognitive function in aged mice and macaques [11][12]. - EV ABPC treatment resulted in a reversal of epigenetic age by over three months in mice and over two years in macaques, indicating significant anti-aging effects [11]. Group 2: Characteristics of ABPC - ABPC, a type of mesenchymal stem cell found in deer antlers, exhibits remarkable regenerative potential, capable of driving rapid bone growth at a rate of 2.75 cm per day, leading to antlers weighing up to 15 kg and measuring 120 cm in three months [10]. - Unlike traditional mesenchymal stem cells, which show signs of aging after 10-15 culture cycles, ABPC maintains its proliferation and regenerative abilities even after 50 culture cycles [10]. - ABPC is noted as the only postnatal mammalian stem cell capable of complete organ regeneration, underscoring its potential as a source for anti-aging therapies [10].
