A molecule known as miR-302b prolongs the life of mice by “waking up” senescent cells — “sleeping” cells that contribute to life-shortening chronic diseases.

Aging &amp; Longevity

Model: 24-month-old female Sprague Dawley rats
Dosage: Undisclosed doses of pig-derived exosomes were injected into the rats every-other-day for eight days starting at day 1 and recommencing at days 68, 181, 280, and 377

Nano-Sized Vesicle Infusions Break Rat Lifespan Record

Nano-sized vesicles called exosomes derived from pig blood plasma significantly extended rat lifespan and broke the record for the longest-living rat.

Harnessing Stem Cells to Fight Aging

Research has uncovered embryonic, induced pluripotent, and adult stem cell therapies with promising results against age-related neurological, diabetic, and reproductive conditions.

Seven different types of stem cells can be used to counter aging-related diseases, but using cellular vesicles associated with their signaling capabilities may be the safest way to harness their therapeutic potential.

Model: Male mice
Dose: Intravenous injection of 100 µL of cold-temperature-exposed exosomes

Cold Exposure Reduces Blood Vessel Hardening while Deterring Senescence

Exposing mice to cold reduces artery calcium buildup and releases vesicles that reduce senescent cells — cells that promote aging.
