Exosomes from human skin cells can stimulate hair growth and could potentially be used for treating hair loss.
research Cyclosporin A-induced hair growth in mice is associated with inhibition of calcineurin-dependent activation of NFAT in follicular keratinocytes
Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
research Plasticity and Cytokinetic Dynamics of the Hair Follicle Mesenchyme During the Hair Growth Cycle: Implications for Growth Control and Hair Follicle Transformations
Disruptions in hair follicle fibroblast dynamics can cause hair growth problems.
research Sustained release of dermal papilla-derived extracellular vesicles from injectable microgel promotes hair growth
Injecting a special gel with human protein particles can help hair grow.
research Hair Growth Defects in Insig-Deficient Mice Caused by Cholesterol Precursor Accumulation and Reversed by Simvastatin
