This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This report suggests that TCDD may alter human epidermal stem cell populations by upregulating c-Myc, potentially leading to increased stem cell turnover during chloracne development.

The study found that aging in hair follicle stem cells leads to hair follicle miniaturization and eventual hair loss in both wild-type mice and humans by proteolyzing type XVII collagen.

In this study, researchers found that the gene Dkk4 influences color pattern formation in domestic cat fetuses, and its mutation is linked to the Ticked pattern type.

This study describes a new two-step method for effectively removing hair particles from split-thickness skin grafts from the scalp, potentially preventing foreign-body reactions at recipient sites.

This study found that endogenous EGF may facilitate the healing of second-degree scald wounds in mice through autocrine, paracrine, and endocrine mechanisms.

This study used 3D bioprinting to implant epidermal stem cells, skin-derived precursors, and Matrigel into mouse wounds, successfully regenerating hair follicles and skin components within four weeks, with minimal impact on stem cell viability and stemness.

This study found that targeting IL-17 signaling in aged skin reduces inflammation and delays age-related traits, suggesting a potential strategy to prevent age-associated skin ailments.

This study found that 11% of cutaneous focal mucinosis lesions demonstrated follicular induction, which can mimic basal cell carcinoma histologically and complicate diagnosis.

This study introduces Immunoguided Cutaneous Regeneration as a potential framework for understanding skin allotransplantation, suggesting that regeneration may depend on the preserved extracellular matrix and a regulated immune response.

Mesenchymal stiffness affects sweat gland cell development.

This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.

This review discusses the role of PRP in treating androgenetic alopecia and alopecia areata, but reports no new clinical results and emphasizes the potential of growth factor signaling as a future therapy.

This study reported that EGFR activation leads to suppression of Stathmin, which may promote synchronized entry into catagen in hair follicles, highlighting potential mechanisms involving EGFR in hair cycle transitions.

In this rat study, Coriaria sinica Maxim extract significantly improved burn wound healing by enhancing epithelial growth and promoting hair regrowth, possibly through early-stage protein and mRNA expression changes.

This chapter reviews surgical management techniques for leukotrichia in vitiligo and presents no new clinical findings; it highlights various grafting and epilation methods.

Cell movements and forces shape feather growth in chicken skin.

This study reported that a composite hydrogel made with Chlorella-derived extracellular polysaccharide–selenium nanoparticles showed strong antibacterial and anti-inflammatory effects in vitro and significantly accelerated wound healing in vivo, offering potential for managing infected wounds and monitoring healing progression.

This study developed a novel hydrogel combining Chlorella extracellular polysaccharide–selenium nanoparticles (EPS-SeNPs) with biocompatible components, which demonstrated strong antibacterial and anti-inflammatory effects, significantly accelerating wound healing in an infected rat model, and enabling pH-based monitoring of healing.

This study found that skin computed tomography may effectively identify epidermoid cysts by revealing features consistent with histopathology, potentially serving as a non-invasive diagnostic alternative to biopsies.

This review summarizes recent discoveries about how tissue-resident stem cells interact with their environments during normal conditions and after injury, without reporting new results.

Laser therapy helped new hair grow in scarred skin for three patients.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

Blocking cell death in certain stem cells can improve wound healing and tissue regeneration.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

This study found that human skin melanocytes with low mutation burdens are smaller, less dendritic, and exhibit stem-like features, often residing in UV-protected hair follicles, suggesting their role in replenishing sun-damaged epidermis.

This review explains that linoleic acid deficiency can lead to skin and growth issues but notes that such deficiencies are rare in well-nourished Western populations; it reports no new clinical findings.

This study observed that earlier-passage keratinocyte cultures led to superior hair follicle neogenesis in dermal-epidermal composites grafted onto immunodeficient mice, suggesting their potential utility in studying human hair follicle development.

In this study, researchers found that moisturizers like Alhydran and DermaCress provided superior hydration and occlusion compared to silicone gel, suggesting these moisturizers may be a patient-friendly and cost-effective alternative for scar management.
