Multimodal Imaging of Hair Follicle Bulge-Derived Stem Cells in a Mouse Model of Traumatic Brain Injury

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

This study reported that bio-pulsed avian-derived mesenchymal stem cell extracellular vesicles significantly improved cell proliferation, wound healing, and gene expression in human skin fibroblasts and hair follicle cells.

New treatments for hair loss could involve using stem cells and a process called the Wnt/beta-catenin pathway to stimulate hair growth.

This study found that loss of the Ptch2 receptor in mice leads to increased incisor growth and enhanced mesenchymal stem cell differentiation, highlighting Ptch2's role in organ regenerative potential.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.
