research Expression Patterns of MITF During Human Cutaneous Embryogenesis: Evidence for Bulge Epithelial Expression and Persistence of Dermal Melanoblasts
Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.
research Aging, Alopecia, and Stem Cells
The document concludes that both internal stem cell factors and external influences like the environment and hormones affect hair loss and aging, with potential treatments focusing on these areas.
research Eph/Ephrin Signaling in Epidermal Differentiation and Disease
Eph/ephrin signaling is important for skin cell behavior and could be targeted to treat skin diseases.
research Congenital Hypotrichosis Due to Short Anagen Phase
Some children are born with unusually short, fine hair because their hair growth phase is short, but this often gets better by itself during puberty.
research Congenital Hair Loss Disorders: Rare, But Not Too Rare
Some hair loss disorders are caused by genetic mutations affecting hair growth.
research Woolly Hair Nevus: A Rare Case with Late Onset in Adolescence
A 17-year-old developed woolly hair nevus in adolescence, which is unusual, and over time the hair darkened and straightened slightly, but microscopic changes persisted.
research The Effect of Tripeptide-Copper Complex on Human Hair Growth In Vitro
A tripeptide-copper complex may help hair grow by increasing cell growth and decreasing cell death.
research Morphological Approach to Hair Disorders
Accurate clinical, histological, and genetic methods are key for understanding and treating hair disorders.
research P53-Dependent Transcriptional Regulation of EDA2R and Its Involvement in Chemotherapy-Induced Hair Loss
The study concludes that the EDA2R gene is activated by p53 during chemotherapy but is not necessary for chemotherapy-induced hair loss.
research Increased Lactate Dehydrogenase Activity Is Dispensable in Squamous Carcinoma Cells of Origin
High lactate dehydrogenase activity is not necessary for the growth of squamous cell carcinoma.
research Mouse Models for the Study of Human Hair Loss
Mice are useful for researching human hair loss and testing treatments, despite some differences between species.
research Regulation of VDR by ΔNp63α Is Associated with Inhibition of Cell Invasion
ΔNp63α helps control a protein that stops cancer cells from spreading.
research Increased Vibrissa Growth in Transgenic Mice Expressing Insulin-Like Growth Factor 1
IGF-1 increases whisker growth in transgenic mice.
research A Composite Model for the Transport of Hydrophilic and Lipophilic Compounds Across the Skin: Steady-State Behavior
The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.
research Hair Physiology and Its Disorders
Different hair growth problems are caused by genetic issues or changes in hair growth cycles, and new treatments are being developed.
research The Role of Immature and Mature Adipocytes in Hair Cycling
Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

The gene p53 is crucial for removing damaged cells to allow for healthy tissue renewal.
research Hairless Is a Nuclear Receptor Corepressor Essential for Skin Function
Hairless protein is crucial for healthy skin and hair, and its malfunction can cause hair loss.
research Mechanism of TAp73 Inhibition by ΔNp63 and Structural Basis of p63/p73 Hetero-Tetramerization
ΔNp63α stops TAp73β from working in skin cancer by blocking its access to specific genes, not by directly interacting with it.
research Alopecia Areata: A Review
Alopecia areata is an autoimmune hair loss condition treated with corticosteroids, and histologic confirmation is the best diagnosis method.
