This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This review discusses the role of cytochrome P450 enzymes in skin metabolism and drug development for skin diseases, highlighting their importance and suggesting further research, but reports no new experimental findings.

This study found that Gelatinase A activity is linked to the absence of type VII collagen during human fetal skin development, indicating its role in remodeling the basement membrane zone.

This study found that a keratin film made from human hair supports enhanced cell proliferation and viability compared to collagen I, suggesting potential for cell culture applications.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This study suggests that ELF5 plays a crucial role as a regulator and maintainer of stem/progenitor cell functions, impacting normal skin development and homeostasis.

Hair keratin protein might help heal mouth wounds faster.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

This study found that in neonatal mice, the absence of the NG2 proteoglycan leads to reduced epidermal thickness and delayed subcutis thickening due to impaired proliferation and adipocyte deficiencies.

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.

In an animal study, researchers observed that simvastatin and Luteolin significantly increased hair growth and reduced hair loss in male mice, with improvements linked to their antioxidant and anti-inflammatory properties.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.

This study reports that cannabinoid receptor type 1 may influence psoriasis development by modulating laminin-511 expression, suggesting a potential target for treatment.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

This study found that local injection of anti-HSV sera in mice provided long-term protection against zoster-like skin lesions and sweating disturbances following an HSV-1 challenge.

This study found that altering cyclin-dependent kinase 4 (CDK4) levels in the bulge region of hair follicles affects the balance of stem cell numbers, potentially influencing hair follicle self-renewal and proliferation.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

This article reviews current advancements and options in skin substitutes for burn patients, but reports no new research findings, noting the promise for fully functional skin substitutes in the future.

In this study, Korean Red Ginseng showed protective effects against chemotherapy-induced premature hair follicle aging in an in vitro model by modulating specific cellular protein expressions.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study found that marine-derived collagen peptides slightly promoted hair matrix proliferation and prolonged hair growth phase in human hair follicles ex vivo, suggesting potential benefits for hair loss treatment.

This study suggests that bovine and fish-derived collagen peptides may help maintain or prolong the hair growth phase and balance hair follicle stem cell populations, potentially benefiting aging and hair loss conditions like androgenetic alopecia.

In this study, researchers found that using a novel Leontopodium alpinum (Edelweiss) extract led to increased hair density and prolonged anagen phase in both ex vivo human hair follicles and a 5-month clinical trial, suggesting potential as an anti-hair loss treatment.

This study found that ingenol mebutate treatment led to gene expression changes in actinic keratoses, with complete lesion clearance in 40% of patients and identified genetic markers potentially predicting treatment response.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

The conclusion is that androgenetic alopecia and senescent alopecia have unique gene changes, suggesting different causes and potential treatments for these hair loss types.
