This review presents clinical and preclinical evidence supporting innovative regenerative approaches to treat vitiligo, as existing treatments lack a specific cure and predictable long-term repigmentation outcomes.

This study found that combining polybrene and a ROCK inhibitor can effectively expand human keratinocyte stem/progenitor cells carrying a transgene, aiding their use in regenerative medicine.

This review discusses current strategies and materials in tissue engineering for skin regeneration, emphasizing design approaches and suggesting directions for future research; it reports no new clinical findings.

This article reviews the steps and methods involved in preparing skin tissues for three-dimensional volumetric imaging, highlighting its potential to provide detailed insights into skin structure not possible with traditional 2D histology, but reports no new findings.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

This study demonstrated how cellular flows and tissue mechanics guide the topological transformations in avian skin, essential for feather follicle development from scales.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

In this study, researchers identified four novel variants in the FGF5 gene associated with the long-haired phenotype in dogs, suggesting additional unexplored genetic factors contribute to this trait beyond the known Lh1-Lh5 alleles.

This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.

A mutation in the KRT74 gene causes tightly curled hair.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.

This study demonstrated that combining the Wnt/β-catenin activator CHIR99021 with 3D spheroid culture effectively enriched hair follicle formation in reconstituted human skin.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

Human hair follicle cells can become fat and bone cells, useful for therapy.

This study found that estrogen affected cell behaviors differently in a scratch-wound assay, increasing VEGF secretion in follicular dermal papilla cells but decreasing it in wounded dermal sheath cells.

This study observed that undifferentiated matrix cells at the base of the hair follicle differentiate into the medulla, cortex, cuticle, and inner root sheath cell types through specific morphological changes.

The study reports that the AVET system showed higher efficiency in transfecting cultured human keratinocytes compared to SuperFect and PrimeFector, with AVET reaching levels of enzyme activity similar to normal cells in keratinocytes from lamellar ichthyosis patients.

This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This study reported that supplementing rat hair follicle stem cells with chick embryo extract enhanced their migration and proliferation, possibly promoting differentiation toward Schwann cells.

This study found histopathological evidence of hypertrophy in nerve endings that may explain the cutaneous neurosensory symptoms in some long COVID-19 patients.

In this study, Ser516 phosphorylation of Artemis was found predominantly in the outer root sheath keratinocytes of hair follicles, suggesting a role in regulating human epidermal appendages.

In this study, the antibody A3 identified quiescent post-progenitor epithelial and mesenchymal cells in developing rat hair follicles, suggesting it may help track the differentiation of these cells.

Eye lens capsules are the best for growing human skin cells.

In this study, miR-221 was identified as a key factor in androgenetic alopecia pathogenesis due to its role in suppressing hair growth by interacting with androgen receptors and affecting related pathways.

This review discusses the potential of cell therapies using dermal papilla and dermal sheath cells for androgenetic alopecia, highlighting their ability to reverse hair follicle miniaturization but not yet achieving significant cosmetic efficacy in trials.

This review examines the mechanisms of hair follicle development and regeneration, discussing current hair loss treatments and emerging therapies like low-level laser therapy and stem cell therapy, which the authors suggest show promise in managing hair loss.
