This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

This report on a case of alopecia areata in a mother and daughter with a 16-year gap suggests genetic predisposition and environmental triggers rather than direct transmission.

This review reports that vitamin D plays an important role in hair follicle development, with a negative correlation observed between serum vitamin D levels and female pattern hair loss, suggesting further research is needed before recommending vitamin D as a treatment.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

Genes controlling hair growth and immune response are disrupted in male pattern baldness.

This study found that adding keratin to a collagen hydrogel improved keratinocyte differentiation compared to a pure collagen hydrogel, particularly when calcium was also present in the media.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This study reports that a plant extract from Orobanche rapum can stimulate skin rejuvenation and protect cutaneous microbiota, potentially creating healthier skin.

In this study, HYDRO DELUXE BIO was reported to show promise for scalp mesotherapy by enhancing angiogenesis and reducing inflammation in an in vitro model.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

This review emphasizes the potential of repurposing topical L-thyroxine for skin ulcers and telogen effluvium and highlights the need for further exploration of its use in dermatology.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

This study identified a unique transcriptional signature in occipital hair follicles that may protect them from miniaturization in androgenetic alopecia, using an animal-free model to investigate gene roles.

Inhibiting Bmp signaling disrupts hair growth and differentiation.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

In this ex vivo and in vitro study, researchers found that capacitive resistive electrical transfer therapy increased cell proliferation and reduced cell death in hair follicles from patients with androgenic alopecia, suggesting potential benefits for alopecia treatment.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This review explores the potential of using genetically-manipulated stem cells as both therapeutic agents and gene delivery vehicles for enhanced wound regeneration, but it reports no new clinical results.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This chapter reviews recent advances in 5α-reductase inhibitors for treating disorders mediated by dihydrotestosterone and reports no new clinical findings.
