Researchers created human hair follicles using a new method that could help treat hair loss.
research Loss-Of-Function Mutations of an Inhibitory Upstream ORF in the Human Hairless Transcript Cause Marie Unna Hereditary Hypotrichosis
Certain mutations in a hair growth-related gene cause a type of genetic hair loss.
research Epigenetic Control of Adult Stem Cell Function
Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.
research Alopecia Areata Profiling Shows TH1, TH2, and IL-23 Cytokine Activation Without Parallel TH17/TH22 Skewing
Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.
research In Vivo Transcriptional Governance of Hair Follicle Stem Cells by Canonical Wnt Regulators
Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.
research Comparative Proteomics Indicates That Biosynthesis of Pectic Precursors Is Important for Cotton Fiber and Arabidopsis Root Hair Elongation
Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.
research Light Scattering from Human Hair Fibers
Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.
research Pharmacologic Inhibition of JAK-STAT Signaling Promotes Hair Growth
Blocking JAK-STAT signaling can lead to hair growth.
research The Harmonies Played by TGF-β in Stem Cell Biology
TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.
research The Immune Functions of Keratinocytes in Skin Wound Healing
Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.
research Hedgehog Stimulates Hair Follicle Neogenesis by Creating Inductive Dermis During Murine Skin Wound Healing
The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.
research Age-Associated Inflammation Inhibits Epidermal Stem Cell Function
Aging causes skin stem cells to work less effectively.
research Tactile Innervation Densities Across the Whole Body
Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.
research A Multicenter, Randomized, Placebo-Controlled, Double-Blind Clinical Trial of a Novel Formulation of 5% Minoxidil Topical Foam Versus Placebo in the Treatment of Androgenetic Alopecia in Men
New 5% minoxidil foam effectively promotes hair growth and is safe for use.
research Molecular Mechanisms of Viral Oncogenesis in Humans
Some viruses can cause cancer by changing cell processes and avoiding the immune system; vaccines and targeted treatments help reduce these cancers.
research Androgen Signaling Regulates SARS-CoV-2 Receptor Levels and Is Associated with Severe COVID-19 Symptoms in Men
Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.
research Stem Cell Heterogeneity and Plasticity in Epithelia
Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
research Finasteride Increases Anagen Hair in Men with Androgenetic Alopecia
Finasteride helps increase hair growth in men with hair loss.
research Complex Hair Cycle Domain Patterns and Regenerative Hair Waves in Living Rodents
Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
research Regulatory T Cells: The Many Faces of Foxp3
Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.
research Stretching the Limits: From Homeostasis to Stem Cell Plasticity in Wound Healing and Cancer
Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
research Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men With Suppressed Testosterone Production
Testosterone's muscle-building effects do not require its conversion to DHT.
research Androgen Sensitivity Gateway to COVID-19 Disease Severity
Men's sensitivity to male hormones might affect how severe COVID-19 gets for them.
research Penetration and Storage of Particles in Human Skin: Perspectives and Safety Aspects
Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.
research Sex Differences in COVID-19: The Role of Androgens in Disease Severity and Progression
Male hormones like testosterone may make COVID-19 worse, and testing for sensitivity to these hormones could help predict how severe a patient's symptoms might be. Treatments that reduce these hormones are being explored.
research Resting No More: Redefining Telogen, the Maintenance Stage of the Hair Growth Cycle
The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
