research Xenobiotica-metabolizing enzymes in the skin of rat, mouse, pig, guinea pig, man, and in human skin models
Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.
research Eccrine sweat glands associate with the human hair follicle within a defined compartment of dermal white adipose tissue
Sweat glands and hair follicles are structurally connected within a specific layer of skin fat.
research Human TSC2-null fibroblast-like cells induce hair follicle neogenesis and hamartoma morphogenesis
Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.
research Two Hypomorphic Alleles of Mouse Ass1 as a New Animal Model of Citrullinemia Type I and Other Hyperammonemic Syndromes
Researchers created a new mouse model for studying Citrullinemia Type I and similar conditions, showing symptoms and treatment responses like those in humans.
research Adult epidermal Notch activity induces dermal accumulation of T cells and neural crest derivatives through upregulation of jagged 1
Activating Notch in adult skin causes T cells and neural crest cells to gather, leading to skin issues.
research Planar cell polarity-dependent and independent functions in the emergence of tissue-scale hair follicle patterns
Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.
research Stem cells and alopecia: a review of pathogenesis
Damaged hair follicle stem cells can cause permanent hair loss, but understanding their role could lead to new treatments.
research Adiponectin Signaling Regulates Lipid Production in Human Sebocytes
Adiponectin boosts lipid production in skin cells, potentially helping treat skin conditions with low sebum.
research Fibromodulin-Deficiency Alters Temporospatial Expression Patterns of Transforming Growth Factor-β Ligands and Receptors during Adult Mouse Skin Wound Healing
Mice lacking fibromodulin have disrupted healing patterns, leading to abnormal skin repair and scarring.
research Inherited epidermolysis bullosa: clinical and therapeutic aspects
The document concludes that inherited epidermolysis bullosa is a challenging genetic condition requiring multidisciplinary care and new treatments.
research Isoproterenol directs hair follicle-associated pluripotent (HAP) stem cells to differentiate in vitro to cardiac muscle cells which can be induced to form beating heart-muscle tissue sheets
Isoproterenol helps hair follicle stem cells turn into beating heart muscle cells.
research Responses of hair follicle–associated structures to loss of planar cell polarity signaling
Loss of Fz6 disrupts hair follicle and associated structures' orientation.
research Combined Deletion of the Vitamin D Receptor and Calcium-Sensing Receptor Delays Wound Re-epithelialization
Removing vitamin D and calcium receptors in mice skin cells slows down skin wound healing.
research The CD44+ALDH+ Population of Human Keratinocytes Is Enriched for Epidermal Stem Cells with Long-Term Repopulating Ability
Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.
research Differential expression of stem cell markers in human follicular bulge and interfollicular epidermal compartments
Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.
research Signalling by senescent melanocytes hyperactivates hair growth
Senescent melanocytes can boost hair growth by activating hair stem cells.
research Essential Role of Polarity Protein Par3 for Epidermal Homeostasis through Regulation of Barrier Function, Keratinocyte Differentiation, and Stem Cell Maintenance
The protein Par3 is crucial for healthy skin, affecting the skin barrier, cell differentiation, and stem cell maintenance.
research Morroniside regulates hair growth and cycle transition via activation of the Wnt/β-catenin signaling pathway
Morroniside may help hair grow and stay in its growth phase by affecting certain cell signals.
research Regulation of melanocyte stem cell behavior by the niche microenvironment
The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.
research The Genetics of Human Skin Disease
Genetic research has advanced our understanding of skin diseases, but complex conditions require an integrative approach for deeper insight.
research Frontal Fibrosing Alopecia: A Review
Frontal Fibrosing Alopecia's cause is unclear, affects mainly postmenopausal women, and current treatments focus on stopping hair loss rather than regrowth.
research Crosstalk between androgen and Wnt/β-catenin leads to changes of wool density in FGF5-knockout sheep
Blocking the FGF5 gene in sheep leads to more fine wool and active hair follicles due to changes in certain cell signaling pathways.
research Alopecia areata
Alopecia areata involves immune response and gene changes affecting hair loss.
research Transgenic mice overexpressing CD109 in the epidermis display decreased inflammation and granulation tissue and improved collagen architecture during wound healing
Mice genetically modified to produce more CD109 in their skin had less inflammation and better healing with less scarring.
research CD34 glycoprotein identifies putative stem cells located in the isthmic region of canine hair follicles
CD34 marks potential stem cells in dog hair follicles.
research Androgens modulate keratinocyte differentiation indirectly through enhancing growth factor production from dermal fibroblasts
Male hormones indirectly affect skin cell development by increasing growth factor levels from skin fibroblasts.
research Epidermal Stem Cells in Hair Follicle Cycling and Skin Regeneration: A View From the Perspective of Inflammation
Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.
