research Gap junctions in Turing-type periodic feather pattern formation
Gap junctions help control feather pattern formation in chickens.
research Alopecia in a Linear Pattern
A 4-year-old boy has a rare type of hair loss in a line pattern on his scalp.
research Gap junctions in Turing-type periodic feather pattern formation
Gap junctions help control feather pattern formation by enabling cell communication.
research Integument pattern formation involves genetic and epigenetic controls: feather arrays simulated by digital hormone models.
Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.
research Developmental Genetics of Color Pattern Establishment in Cats
Gene expression, especially Dkk4, is key to cat color patterns.
research Developmental genetics of color pattern establishment in cats
Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.
research Atypical Morphological Patterns of Alopecia Areata with Trichoscopic and Histopathologic Correlation: A Case Series
Recognizing unusual patterns of hair loss helps dermatologists diagnose and manage Alopecia Areata better.
research Feather arrays are patterned by interacting signalling and cell density waves
Feather patterns in birds are shaped by signaling interactions and cell movements, with EDA/EDAR crucial for pattern formation.
research A Simple Technique for Revealing the Surface Pattern of Hair
A simple method can show hair's surface pattern.
research "Curly" Wood and Tiger Tails
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research Topology of Feather Melanocyte Progenitor Niche Allows Complex Pigment Patterns to Emerge
Feather pigment patterns form through melanocyte arrangement and simple regulatory mechanisms.
research A Comprehensive Approach to Hair Pathology of Horizontal Sections
A new method using visual aids to diagnose hair diseases was effective after brief training.
research Trichoscopic patterns of nonscarring alopecia's
Different patterns on the scalp help diagnose types of hair loss without needing a biopsy.
research The Ziering Whorl Classification of Scalp Hair
Craig Ziering created a system to classify scalp hair patterns, important for improving hair restoration surgery results.
research Unilateral heterochromia of scalp hair with adjacent hypomelanotic skin lesions
The boy's hair and skin color differences are due to a pigmentation disorder.
research Region-specific reversal of epidermal planar polarity in the rosette fancy mouse
Hair follicles in the back of the rosette fancy mouse have reversed orientations due to a gene mutation.
research Hair and nail disorders
Hair and nail disorders can cause changes in scalp pigmentation, especially with sun exposure and alopecia.
research Pattern Formation
The conclusion is that understanding how patterns form in biology is crucial for advancing research and medical science.
research The Ziering Whorl Classification of Scalp Hair
The conclusion is that creating natural-looking hair restoration requires replicating natural scalp whorl patterns and inserting grafts at specific angles.
research Trichoscopy of dissecting cellulitis of the scalp: Exclamation mark hairs and white dots as markers of disease chronicity
Exclamation mark hairs suggest early scalp disease, while white dots indicate it's chronic.
research Making Waves with Hairs
Skin patterns are formed by simple reaction-diffusion mechanisms.

research Clinical repigmentation patterns in paediatric vitiligo
The study found that the most common repigmentation pattern in children with vitiligo is a combination of patterns, with a new medium spotted pattern identified.
research Colored dots on trichoscopy—beware of artifacts
Some hair products can create false signs on scalp examinations, leading to wrong diagnoses.
