The Claim
In aged mice, intranasal administration of hiPSC-NSC-EVs induces widespread transcriptomic changes in hippocampal microglia, characterized by upregulation of mitochondrial and antioxidant genes and downregulation of neuroinflammatory pathways including TLR, MAPK, TNF, and IL-17 signaling.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older mice, delivering extracellular vesicles from stem cells through the nose alters gene activity in brain immune cells, increasing expression of genes involved in energy production and stress defense while decreasing expression of genes linked to inflammation.

Tiny bubbles from stem cells, sprayed into the nose, travel to the brain and get absorbed by immune cells there. These bubbles carry special molecules that turn down genes causing inflammation and turn up genes that help the cells produce energy more efficiently. This calms down the overactive immune cells and helps them work better, reducing damage to brain tissue.
