research Emerging interactions between skin stem cells and their niches
Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.
research Morphogenesis, Growth Cycle and Molecular Regulation of Hair Follicles
Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.
research 837 From genotoxic stresses to skin damage: Distinct, novel mechanisms of skin and hair damage in chemo/radiation therapy
Chemotherapy and radiation therapy cause skin and hair damage by altering gene expression and signaling pathways.
research Wnt signaling in skin organogenesis
Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.
research Epidermal Development in Mammals: Key Regulators, Signals from Beneath, and Stem Cells
Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.
research Bioengineering a 3D integumentary organ system from iPS cells using an in vivo transplantation model
Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.
research Biomaterial-based mechanical regulation facilitates scarless wound healing with functional skin appendage regeneration
Biomaterials can help heal wounds without scars and regenerate skin features.
research A transient dermal niche and dual epidermal programs underlie sweat gland development
Sweat gland development involves two unique skin cell programs and a temporary skin environment.
research Disrupted Ectodermal Organ Morphogenesis in Mice with a Conditional Histone Deacetylase 1, 2 Deletion in the Epidermis
Mice without certain skin proteins had abnormal skin and hair development.
research Nevoid basal carcinoma syndrome (Gorlin syndrome) and pronounced androgenic alopecia in a woman with a novel mutation p.Leu1159fsx32 in the PTCH gene
A woman with a new PTCH gene mutation has both Gorlin syndrome and severe hair loss.
research Isoxazole 9 (ISX9), a small molecule targeting Axin, activates Wnt/β‐catenin signalling and promotes hair regrowth
Isoxazole 9 (ISX9) may help regrow hair by activating certain cell signals.
research Development and Maintenance of Epidermal Stem Cells in Skin Adnexa
Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.
research ISX9, a small molecule targeting Axin, activates Wnt/β-catenin signaling and promotes hair regrowth
ISX9 helps regrow hair by activating a specific cell signaling pathway.
research Transcriptomic insights into the effects of tyrosine on sub-Columbian plumage in H line chickens
A 1.0% tyrosine diet increases melanin in chicken feathers.
research Immunopathogenesis of Primary Cicatricial Alopecia
Hair loss in Lichen Planopilaris is caused by immune system issues damaging hair follicles and stem cells.
research The Hair Follicle
Dogs could be good models for studying human hair growth and hair loss.
research Genome-wide Maps of Histone Modifications Unwind In Vivo Chromatin States of the Hair Follicle Lineage
Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.
research Immunolocalization of a Histidine-Rich Epidermal Differentiation Protein in the Chicken Supports the Hypothesis of an Evolutionary Developmental Link between the Embryonic Subperiderm and Feather Barbs and Barbules
A specific protein in chicken embryos links early skin layers to feather development.
research Stem cell factor/c-Kit signalling in normal and androgenetic alopecia hair follicles
SCF and c-Kit decrease in AGA hair follicles, possibly affecting hair pigmentation and growth.
research Expression ofSfrp2Is Increased in Catagen of Hair Follicles and Inhibits Keratinocyte Proliferation
Sfrp2 increases during hair follicle catagen phase and slows keratinocyte growth.
research Hair follicles’ transit-amplifying cells govern concurrent dermal adipocyte production through Sonic Hedgehog
Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.
research External light activates hair follicle stem cells through eyes via an ipRGC–SCN–sympathetic neural pathway
Light can turn on hair growth cells through a nerve path starting in the eyes.
research Morpho‐regulation in diverse chicken feather formation: Integrating branching modules and sex hormone‐dependent morpho‐regulatory modules
Sex hormones, especially estradiol, can change chicken feather shapes and colors.
research Dissecting the boundary of quiescence and activation of murine melanocyte stem cells in the hair follicle niche
Melanocyte stem cells in hair follicles are key to understanding and potentially preventing hair graying.
research Trans‐species hair growth induction by human hair follicle dermal papillae
Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.
research The role of hair follicles and Edar signalling in cutaneous wound healing
Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.
research Organogenesis From Dissociated Cells: Generation of Mature Cycling Hair Follicles From Skin-Derived Cells
