What Is Homing?
Homing is the phenomenon in which stem cells recognize damaged or inflamed tissue on their own and migrate toward it. It is much like finding one's way back home.
The Role of SDF-1 and CXCR4/CXCR7 Receptors
Damaged tissue secretes a chemokine called SDF-1, which the CXCR4 and CXCR7 receptors on the stem-cell surface recognize. Through this interaction the stem cells migrate to the injured area.
In particular, stem cells with higher CXCR4/CXCR7 expression show a stronger homing effect and improved treatment efficiency.
How Homing Works
- Detecting signals sent by damaged tissue
- Migrating autonomously to the damaged area along the bloodstream
- Supporting tissue regeneration
- Modulating the inflammatory response
- Cell-to-cell cooperation through chemokines and cytokines
