research URB expression in human dermal papilla cells
The gene URB is more active in human hair growth cells and responds to a hair-related hormone.
research Abstracts
The document reports findings on genetic research, including ethical concerns about genome editing, improved diagnosis of mitochondrial mutations, solving inherited eye diseases, confirming gene roles in epilepsy, linking a gene to aneurysms, and identifying genes associated with age-related macular degeneration.
research Editors' Picks
ANp63 is crucial for skin integrity, new filaggrin gene mutations link to eczema, hair can regrow from non-stem cells, sunburns are increasing, and glucocorticoids help treat skin allergies by affecting immune cells.
research News in brief
Researchers found potential new targets for treating melanoma and nonmelanoma skin cancers, and identified a possible cause and treatment for male pattern baldness and eczema.
research 250 Sweat glands shrink upward with aging, causing dermal layer defects that lead to loss of skin elasticity and wrinkling-establishment of 3D imaging method for skin appendages
Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.
research 251 Morphogenetic events in hair follicle heterotypic spheroids
The research concluded that hyaluronic acid affects the formation and growth of hair follicle-like structures in a lab setting.
research Human Hair as a Testing Substrate in the Era of Precision Medicine: Potential Role of ‘Omics-Based Approaches
Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.
research Fibroblast heterogeneity: implications for human disease
Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.
research Prostaglandin D 2 Inhibits Hair Growth and Is Elevated in Bald Scalp of Men with Androgenetic Alopecia
PGD2 stops hair growth and is higher in bald men with AGA.
research Macrophages Contribute to the Cyclic Activation of Adult Hair Follicle Stem Cells
Macrophages help activate hair follicle stem cells, affecting hair growth and skin repair.
research Vitamin D and the skin: Physiology and pathophysiology
Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.
research Oxidative stress in ageing of hair
Oxidative stress contributes to hair graying and loss as we age.
research Biology of the wool follicle: an excursion into a unique tissue interaction system waiting to be re‐discovered
The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.
research Prolactin—a novel neuroendocrine regulator of human keratin expressionin situ
Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.
research The impact of oxidative stress on hair
Oxidative stress damages hair and contributes to aging, and managing it can help maintain hair health.
research Stem cell plasticity enables hair regeneration following Lgr5+ cell loss
Hair can regrow after certain stem cells are lost because other stem cells can take over their role.
research Pitx2, a β-catenin-regulated transcription factor, regulates the differentiation of outer root sheath cells cultured in vitro
Pitx2 helps outer root sheath cells differentiate but can't start hair growth on its own.
research Skin physiology in microgravity: a 3-month stay aboard ISS induces dermal atrophy and affects cutaneous muscle and hair follicles cycling in mice
A 3-month stay in space causes skin thinning, disrupts hair growth, and changes muscle-related genes in mice.
research Primary cicatricial alopecia: Recent advances in understanding and management
New understanding of the causes of primary cicatricial alopecia has led to better diagnosis and potential new treatments.
research A cell-based system for screening hair growth-promoting agents
Apigenin may help promote hair growth and could treat hair loss.
research Sp6 downregulation of follistatin gene expression in ameloblasts
Sp6 promotes tooth development by reducing follistatin levels.
research Cell Cycle Regulation and Regeneration
Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.
research Expression and function of nuclear receptor co-activator 4: evidence of a potential role independent of co-activator activity
NcoA4 may have roles beyond helping control gene activity, possibly affecting cell behavior and stability.
research Arctiin blocks hydrogen peroxide-induced senescence and cell death though microRNA expression changes in human dermal papilla cells

research ILK modulates epithelial polarity and matrix formation in hair follicles
ILK is essential for proper hair follicle development and structure.
research Analysis of the microRNA expression profile of normal human dermal papilla cells treated with 5α-dihydrotestosterone
DHT affects hair follicle cells by changing microRNA levels, leading to less cell growth and more cell death.
research Telomere dysfunction impairs epidermal stem cell specification and differentiation by disrupting BMP/pSmad/P63 signaling
Telomere damage affects skin and hair follicle stem cells by messing up important growth signals.
