Study in Cell: SRCs Injection Slows Systemic Aging in Primates
Chinese scientists have identified a potential method to decelerate the aging process by developing specialized stem cells that are resistant to age-related changes. Published in Cell, an experiment conducted on macaques revealed that these cells effectively slowed systemic aging, enhanced brain function, and even partially restored reproductive capabilities.
These novel cells, termed SRCs (senescence-resistant cells), were administered intravenously to elderly primates over a period of 44 weeks, with close monitoring of their effects. The outcomes were remarkable: a significant reduction in `senescent` cells was observed in the animals, along with decreased inflammation and tissue degradation. Furthermore, the cells contributed to strengthening brain health, improving memory, and mitigating age-related decline in the reproductive system.
Researchers attribute the rejuvenating effects partly to exosomes – microscopic vesicles secreted by SRCs that play a crucial role in combating cellular senescence. Importantly, no serious adverse side effects were recorded throughout the entire duration of the experiment, highlighting the potential safety of this new approach.
The researchers hail these findings as “the first evidence” that genetically modified stem cells can genuinely slow down aging in primates. The next critical step involves determining the safety and applicability of this approach for human use, paving the way for potential future anti-aging therapies.
