This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

In this study, researchers used 3D bioprinting with skin stem cells and specific hydrogels to create artificial skin that successfully promoted complete wound healing and the regeneration of skin structures, including hair follicles and blood vessels, in mice.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

In this review, the authors highlight the crucial role of mesenchymal stem cells in dermatologic therapies, noting their potential to enhance skin structure and appearance through regenerative mechanisms like inflammation induction, angiogenesis, and recruitment of tissue-specific progenitors.

This study found that Sol/ASC-DP nanoparticles could enhance the skin permeability of minoxidil due to improved stability and hydrophobic interactions in the nanoparticle structure.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This expert opinion article presents insights from dermatologists and aesthetic physicians on using polynucleotides (Rejuran®) for skin hydration, rejuvenation, structural support, barrier repair, and scar remodeling, noting their favorable safety profile but highlighting the need for more robust evidence and research.

This study validated the HS 3D-SeboSkin model as a reliable tool for preclinical research, effectively preserving the structure and biomarker expression of lesional and perilesional HS skin ex vivo.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

This review reports that the unique tunnel structures in advanced hidradenitis suppurativa impair quality of life and resist biological therapy, with their formation involving complex cellular and molecular interactions, including microbial dysbiosis, all contributing to ongoing inflammation and scarring.

This review discusses the structural properties, pharmacological effects, and clinical applications of neurotoxins on synapses, reporting no new experimental results.

This study found that subcutaneous injection of a CXCL12 neutralizing antibody significantly promoted hair growth in androgenic alopecia and inhibited hair loss in alopecia areata in mouse models, suggesting its potential as a promising treatment for hair loss.

This review discusses how menopause affects skin structure and function, finding associations between menopause and common skin conditions, but reports no new clinical results.

This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.
