research Hair Cortisol: A Biomarker of Chronic Stress in Animals and its Association with Reproduction
High levels of cortisol in hair show long-term stress which can lower fertility in animals.
research From signal to form: Nod factor as a morhogenetic signal molecule to induce symbiotic responses in legume root hairs
Nod factor can trigger changes in legume root hairs with just one molecule.
research Col4a2-eGFPmouse model reveals the molecular and functional dynamics of basement membrane remodelling in hair follicle morphogenesis
Scientists made a mouse that shows how a specific protein in the skin changes and affects hair growth and shape.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research Neural crest cells give rise to non-myogenic mesenchymal tissue in the adult murid ear pinna
Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.
research Curl secret in cells
Hair curliness is caused by the arrangement and length of two different cell types.
research Ultrastructure of two types of glandular hairs of salvia farinacea benth during development
Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.
research The heart of the hair fiber: How the inner structure of the coat reflects adaptive variation across color, sex, age, and body region in dromedary camels (Camelus dromedarius)
Camel hair structure, not color, helps camels stay cool in the desert.
research Visual Vignette
A 13-year-old boy with Cushing syndrome has high cortisol levels from a pituitary gland issue and underdeveloped sexual characteristics.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Perceived predation risk predicts glucocorticoid hormones, but not reproductive success in a colonial rodent
Prairie dogs with fewer neighbors are more stressed but their number of babies isn't affected.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Human hair keratin network and curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Evaluation of Hair Characteristics and Animal Age on the Impact of Hair Cortisol Concentration in Feedlot Steers
Older steers have higher hair cortisol levels than younger steers.
research Cultured human skin fibroblasts: a model for the study of androgen action
research Ear pinna growth and differentiation is conserved in murids and requires BMP signaling for chondrocyte proliferation
BMP5 is essential for ear cartilage cell growth in rodents.
research Hair Cortisol Measurements in the Evaluation of Cushing's Syndrome
Proximal hair cortisol is a reliable tool for diagnosing Cushing's Syndrome.
research Applications of Hair as a Record of Systemic Exposure to Cortisol
Hair cortisol content can indicate cortisol exposure and varies with age, puberty, and BMI in youth.
research Differential expression levels of Sox9 in early neocortical radial glial cells regulate the decision between stem cell maintenance and differentiation
Sox9 levels in brain stem cells affect whether they stay as stem cells or become neurons.
research A STUDY OF THE DIFFERENTIATION PRODUCTS OF THE HAIR FOLLICLE CELLS WITH THE ELECTRON MICROSCOPE.
Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.
research Extraction and Analysis of Cortisol from Human and Monkey Hair
The method effectively measures long-term stress levels using hair samples.
research Alarm reaction of pilosebaceous apparatus
The hair and oil glands react by changing structure when stressed.
research Attraction of sensory fibers by Merkel cells during co-culture of sensory ganglia and hair follcies in collagen-gel
research Banding Pattern on Polarized Hair Microscopic Examination and Unilateral Polymicrogyria in a Patient With Steroid Sulfatase Deficiency
A patient with steroid sulfatase deficiency had a unique hair pattern and a brain malformation not previously linked to the condition.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research Number changes and development potential of wool follicle cells in the early stages of fiber differentiation
Wool follicle cells are more complex than previously thought.
research Quantifying whole human hair scalp fibres of varying curl: A micro‐computed tomographic study
Human hair varies in structure based on curl type, with high curl hair showing the most differences.
research Correlation between Scalp Hair Morphology, Haematological Parameters and Glycaemic Status in Individuals with Diabetes Mellitus
Diabetes can cause hair thinning, increased hair loss, and changes in hair growth phases.
