This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

In this study, researchers observed that epidermal damage may increase susceptibility to Bacillus anthracis infection, allowing it access through hair follicles and the denuded dermis in mice.

This study found that skin thickness in Bakerwali goats increased with age, with notable histological differences in these layers across diverse regions of the body.

In this study, the staining properties of two types of cysts, epidermal and pilar, were found to differ, supporting their origins from the epidermis and the trichilemmal hair follicle layer, respectively.

This study suggests that using sebaceous glands from rat tail skin samples may effectively capture hair follicle stem cells, potentially aiding skin regenerative medicine when available tissue is limited.

This study developed microfluidic-assisted GelMA-MSC/HAD-EPC microspheres that efficiently generated hair follicles in nude mice, suggesting a promising strategy for advancing hair-regenerative medicine.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

This review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

This study found that loss of integrin-β4 or its ligand, laminin-α3β3ɣ2, in keratinocytes increases differentiation via delamination, and demonstrated a role for hemidesmosomes in epidermal differentiation through both mitotic and non-mitotic mechanisms, influenced by Notch signaling.

This study found that epidermal stem cells are located in rats' hair follicle bulge regions, and the methods used to isolate and culture these cells in vitro are feasible.

In this study, a dual-layer electrospun nanofibrous mat incorporating chitosan nanoparticles, growth factors, and hair follicle bulge stem cells significantly enhanced wound healing in a rat model.

This study developed a novel regenerative platform using nanozyme-enabled materials combined with exosomes and laser stimulation to enhance wound healing in a mouse model, which more effectively regulated reactive oxygen species and improved early angiogenesis and collagen organization compared to conventional methods.

This study suggests that a portable OCT system may be useful for the clinical diagnosis and evaluation of skin diseases and laser treatment outcomes.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

This study found that spatial transcriptomics can reveal hidden inflammation patterns in atopic dermatitis by correlating epidermal and dermal gene expression levels, improving understanding of skin pathology.

This study suggests that the exercise-induced cytokine IL-15 can improve wound healing in aged skin, along with previously reported benefits on skin structure and mitochondrial function.

This study observed that patients with different types of alopecia exhibited variable epidermal thickness and consistent dermal changes, including hair follicle destruction and lymphohistiocytic infiltrates, which may suggest inflammation.

In this study, long-pulsed 755-nm alexandrite laser treatment for keratosis pilaris significantly improved skin roughness and redness, as well as follicular plug reduction, with good safety and patient satisfaction compared to a moisturizing lotion alone.

This study found that lasers and light devices may alleviate recalcitrant skin side effects in cancer patients treated with EGFR inhibitors, offering an alternative for those who do not respond to traditional therapies.

This article discusses the effects of ablative carbon dioxide laser treatment for skin rejuvenation, noting it requires only a single treatment but involves more complex postoperative management, without reporting new clinical outcomes.

This abstract discusses the mechanism and effects of ablative carbon dioxide laser treatment for skin tightening, reporting no new clinical results but noting the need for involved postoperative management.

In this study, despite morphological differences in the hair growth cycle stages, the lipid composition of the epidermis and dermis showed no significant variation, though water content and cholesterol levels differed between these skin layers.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study reported that the absence of Lsh in skin led to significant epidermal hyperplasia and altered gene expression, suggesting its crucial role in regulating epidermal proliferation, differentiation, and wound healing.

This study found that excess vitamin A in organ cultures of mouse embryos led to significant changes in epidermis and hair follicles, altering morphogenesis and polysaccharide distribution.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.
