This study presents a new model for androgenetic alopecia progression, explaining diffuse hair loss in women through 3D reconstructions of the arrector pili muscle and its relationship with the hair follicle stem cell niche.

This review summarizes the anatomy and physiology of the arrector pili muscle and discusses its potential role in hair loss disorders, reporting no new clinical results.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This study found that chitosan and surface-deacetylated chitin nanofibrils promoted hair growth in mice and increased fibroblast growth factor-7 production in human follicle dermal papilla cells.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This article discusses the advances in understanding wound-induced hair follicle neogenesis (WIHN) and highlights the roles of specific signaling pathways and cellular plasticity, noting no clinical results but suggesting potential areas for further research.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This research reviews the roles of dermal papilla signaling in hair follicle development and suggests new genetic tools could advance bioengineering therapies for alopecia, but it reports no new results.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

In this study, topical tofacitinib significantly increased hair regrowth in mice compared to minoxidil or vehicle, potentially due to elevated VEGF levels and reduced inflammation.

This review discusses the paracrine properties of cardiac stem cells and pericytes in regenerative medicine for ischaemic diseases and reports no new clinical results.

This study found that Gsdma3 mutation in mice allows hair follicles to bypass a typical telogen phase and directly enter the anagen phase, suggesting Gsdma3's role in hair cycle transitions by regulating Wnt signaling.

This review discusses genome-wide association studies in dermatology, noting that variants linked to risk for 10 skin complex diseases have been identified, with potential implications for diagnostics and management; it reports no new clinical results.

In this study, a dual recombinase-mediated genetic system showed that cavity macrophages accumulate on the surface of visceral organs during lung and liver injury but do not penetrate or contribute to tissue repair.
