Researchers have shown that serotonin directly stimulates dermal papilla cells and promotes hair growth in lab-grown hair ...

Rather, the stress hormone prevented dermal papilla cells from secreting Gas6, a molecule that the researchers showed can activate the hair follicle stem cells,” reads the release.

“At different times during the hair follicle life cycle, the very same dermal papilla cells can send signals that either keep follicles dormant or trigger new hair growth,” said Maksim Plikus ...

Without this exchange, the hair follicles did not grow or make hair. Nearly all of the signature proteins that Rendl and Fuchs tested in dermal papilla cells decreased when they deleted the BMP ...

Hair growth is regulated by a small cluster of hair-specific fibroblasts, the dermal papilla. ... Hair follicle dermal condensation forms via Fgf20 primed cell cycle exit, ...

Microenvironmental reprogramming by three-dimensional culture enables dermal papilla cells to induce de novo human hair-follicle growth; Claire A. Higgins, James C. Chen, Jane E. Cerise, Colin A ...

In five of the seven samples, the transplanted dermal papilla cells induced new hair follicles to grow in the skin graft. A DNA test confirmed that these hair follicles were, indeed, a genetic ...

Once inside the hair follicle, Hill says the stress hormone causes the melanocytes in the dermal papilla — which houses all the cells that determine hair's characteristics, per the Journal of ...

Hair growth is regulated by a small cluster of hair-specific fibroblasts, the dermal papilla. But exactly how dermal papilla forms has remained elusive until now. In a recent study, research ...

That's important, because "dormant hair follicles cannot be restored, therefore cannot regenerate hair," she said. Still, a cure for balding pates isn't around the corner, Rendl stressed.
