July 2025 in “Biochimica et Biophysica Acta (BBA) - Molecular Cell Research” In this study, researchers identified the miR-22-3p/CLIC4 signaling pathway as a key regulator in hair follicle miniaturization among androgenetic alopecia models, suggesting that targeting CLIC4-mediated sonic hedgehog pathway disruption may offer new therapeutic strategies for AGA treatment.
March 2025 in “Stem Cell Research & Therapy” This study found that microneedles containing magnetic intracellular vesicles and tremella polysaccharide improved the hair microenvironment and accelerated hair regeneration in mice with androgenic alopecia.
April 2019 in “Journal of Investigative Dermatology” In this study, engineered mice with a mutation similar to that in Olmsted syndrome showed progressive hair loss due to impaired inner root sheath keratinocyte differentiation and stem cell exhaustion.

February 2018 in “PubMed” This study suggests that minoxidil may promote hair growth in androgenetic alopecia by increasing intracellular calcium, which enhances stem cell differentiation, offering insights for new drug development.
October 2025 in “Gene Expression” This review explores the potential of exosomes, which contain substances that may stimulate hair follicle activity, as a new therapeutic strategy for alopecia, and discusses their possible benefits and risks based on current knowledge of microRNAs and intracellular signaling in hair follicle morphogenesis.
