Could Aging Leave a "Memory" That Spreads and Even Passes to the Next Generation?

A new aging model posits that aging imprints signatures across molecular, tissue, and organ system levels, and these signatures may also transmit across generations.

Scientists Discover Deer Antler Stem Cells That Reverse Aging in Mice and Monkeys

Researchers discover that deer antler stem cells can restore bone density, slow aging, and reverse biological age in mice and primates.

<p>Model: 5xFAD mice</p>
<p>Dosage: 5-µL sprayed into each nostril at concentrations of 30 × 109/100 µL once weekly for two weeks</p>


Exploring a Nasal Spray that Might Delay Alzheimer’s Progression by Years

Researchers use nano-sized vesicles derived from neural stem cells to preserve cognition as well as reduce brain inflammation and plaque buildup in an Alzheimer’s mouse model.
