Live imaging of stem cell and progeny behaviour in physiological hair-follicle regeneration
July 2012
in “Nature”
TLDR Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.
This study used live imaging to observe the behavior of stem cells and their progeny during hair follicle regeneration in mice. The researchers found that hair regeneration involves dynamic cellular behaviors and relies on the presence of the mesenchyme. Ablation of the mesenchymal dermal papilla resulted in impaired hair follicle growth, indicating the importance of epithelial-mesenchymal interactions for stem cell activation and regeneration. The study's findings may be relevant to other tissues and could advance the use of stem cells in regenerative medicine.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.
