This study found that hair follicles in mice and humans can convert wound-related myofibroblasts into adipocytes, suggesting a potential pathway to reduce scar formation by activating BMP signaling.

COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem cells.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This study found that Hoxc13 mutations in mice cause defects in hair, nail, and tongue structures, with the most noticeable issue being brittle hair leading to alopecia.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This review explores the evolution and development of skin-associated adipose tissue and proposes new nomenclature for the cells and adipose tissue underlying the reticular dermis, without reporting clinical results.

This study found that sebaceous-gland-derived glycerol significantly contributes to stratum corneum hydration in mice with sebaceous gland deficiencies.

This study found that desmocollin 1 is crucial for strong adhesion and barrier maintenance in the mouse epidermis, with its absence leading to skin and hair issues resembling chronic dermatitis.

This review explores the potential health benefits of food bioactive compounds, specifically polyphenols, as preventive agents against non-communicable diseases like cancer and cardiovascular disorders, while also addressing challenges like bioavailability and industrial applications.

This review discusses the pharmacology and toxicology of cyclooxygenase in skin, highlighting its role in inflammation, wound healing, and tumorigenesis, without presenting new clinical results.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This study found that human hair follicles serve as a crucial reservoir for Langerhans cells, which repopulate the epidermis depleted by ultraviolet B exposure.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This review outlines key considerations for designing fluorescence microscopy experiments in cell biology, discussing the importance of hardware availability, suitability of biological models, and imaging agents to achieve high-resolution and informative images.

This article discusses the role of stratum corneum disruption in dandruff and suggests that treatments improving scalp barrier integrity along with antifungal activity may be beneficial; it reports no new research findings.

This study found that activating autophagy with specific small molecules and drugs can stimulate hair growth by initiating the anagen phase in dormant hair follicles, suggesting a potential treatment for hair loss.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This article proposes a hypothesis that hyperandrogenemia is the final common pathway for developing adolescent PCOS and emphasizes the importance of reducing androgen levels to mitigate risks of metabolic syndrome, diabetes, and infertility in adulthood.

In this study, researchers found that connexin 43-negative cells in the basal layer of the epidermis could serve as markers for keratinocyte stem cells, aiding their identification and separation.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

This study discovered that TREM2 macrophages influenced by squalene play a role in acne's development by hindering the killing of Cutibacterium acnes, helping explain why benzoyl peroxide is effective in treatment.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study found that electroosmotic flow through hair follicles significantly contributes to solution flow during iontophoresis in hairless mouse skin.
