research Sparse Hair on the Scalp
A 5-year-old girl has sparse, dry, and brittle hair but is otherwise healthy.
research Trps1 activates a network of secreted Wnt inhibitors and transcription factors crucial to vibrissa follicle morphogenesis
Trps1 is essential for proper hair follicle development.
research Morphogenesis of chimeric hair follicles in engineered skin substitutes with human keratinocytes and murine dermal papilla cells
Engineered skin can grow chimeric hair follicles only with mouse dermal papilla cells.
research 859 Building a functional niche for hair follicle stem cells
Deleting the CRIF1 gene in mice disrupts skin and hair formation, certain proteins affect hair growth, a new compound may improve skin and hair health, blood cell-derived stem cells can create skin-like structures, and hair follicle stem cells come from embryonic cells needing specific signals for development.
research Premature termination of hair follicle morphogenesis and accelerated hair follicle cycling in Iasi congenital atrichia (fzica) mice points to fuzzy as a key element of hair cycle control
The fuzzy gene is crucial for controlling hair growth cycles.
research The Proteins of Hair and Other Hard α-Keratins
research Uncombable hair (pili trianguli et Canaliculi): Evidence for dominant inheritance with complete penetrance based on scanning electron microscopy
Uncombable hair is inherited dominantly with complete penetrance.
research Hair Vibrissa Follicle Morphogenesis is Linked to the Expression of Retinoic Acid Receptors α and γ Genes
Retinoic acid receptors are important for hair follicle development.
research [Contribution to hair medulla study (author's transl)].
Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.
research Expression of type I hair keratins in follicular tumours
Pilomatrixomas likely originate from the hair matrix due to changes in hair keratin expression.
research The mesenchymal component of hair follicle neogenesis: background, methods and molecular characterization
The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.
research Sequences and differential expression of three novel human type-II hair keratins
Hair differentiation starts earlier than thought, involving multiple type-II keratins.
research De novo filament formation by human hair keratins K85 and K35 follows a filament development pattern distinct from cytokeratin filament networks
Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.
research Hair follicle embryogenesis in the human. Characterization of events in vivo and in vitro.
The document explains how hair follicles develop in humans.
research Omics for Precious Rare Biosamples: Characterization of Ancient Human Hair by a Proteomic Approach
The study developed a method to analyze ancient hair proteins using very small samples.
research Early inductive events in ectodermal appendage morphogenesis
Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research Morphogenesis and Renewal of Hair Follicles from Adult Multipotent Stem Cells
Adult mouse skin contains stem cells that can create new hair, skin, and oil glands.
research Molecular evolution of the keratin associated protein gene family in mammals, role in the evolution of mammalian hair
KRTAP genes evolved early in mammals, leading to diverse hair traits.
research An Integrated Transcriptome Atlas of Embryonic Hair Follicle Progenitors, Their Niche, and the Developing Skin
The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.
research 883 Hair follicle bulb developed as 3D scaffold free microtissue
Scientists created a tiny, 3D model of a hair follicle that grows and acts like a real one.
research Sox13 is a novel early marker for hair follicle development
Sox13 is a useful marker for early hair follicle development but not essential for hair growth.
research Demonstration of Inherent Electromagnetic Energy Emanating from Isolated Human Hairs.
Human hair has electromagnetic properties.
research Co-option of Hair Follicle Keratins into Amelogenesis Is Associated with the Evolution of Prismatic Enamel: A Hypothesis
Hair follicle keratin may have been used in tooth enamel evolution.
research Prolactin and Its Receptor Are Expressed in Murine Hair Follicle Epithelium, Show Hair Cycle-Dependent Expression, and Induce Catagen
Prolactin affects hair growth cycles and can cause early hair follicle regression.
research Polyclonal origin and hair induction ability of dermal papillae in neonatal and adult mouse back skin
Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.
research 1390 Active hair growth is fuelled by conveyor-belt like differentiation of germinative layer cells
Hair growth is driven by cells that move and change like a conveyor belt.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.
