research Mesenchyme governs hair follicle induction
The mesenchyme can start hair growth, but the exact signal that causes this is still unknown.
research Wnt signaling in skin organogenesis
Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.
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 The Transcriptional Regulator Prdm1 Is Essential for the Early Development of the Sensory Whisker Follicle and Is Linked to the Beta-Catenin First Dermal Signal
Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.
research Developmental and evolutionary comparative analysis of a regulatory landscape in mouse and chicken
Gene regulation evolved differently in mouse and chicken skin, but remained stable in their trunks.
research Ectodermal Organ Stem Cells: Morphogenesis, Population Regenerative Behavior, and Evo-Devo
Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.
research The Wnt inhibitor, Dickkopf 4, is induced by canonical Wnt signaling during ectodermal appendage morphogenesis
The study found that the protein Dkk4 helps regulate hair growth by controlling Wnt signaling in mice.
research Rooster feathering, androgenic alopecia, and hormone-dependent tumor growth: What is in common?
Sex hormones affect hair and feather growth and may help manage alopecia and hormone-dependent cancers.
research Distinct mechanisms underlie pattern formation in the skin and skin appendages
Different processes create patterns in skin and things like hair and feathers.
research BMP2 and BMP7 play antagonistic roles in feather induction
BMP2 and BMP7 have opposite roles in feather formation.
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 Identification of dkk4 as a target of Eda-A1/Edar pathway reveals an unexpected role of ectodysplasin as inhibitor of Wnt signalling in ectodermal placodes
Ectodysplasin inhibits Wnt signaling to help form hair follicles.
research Identification of a secreted BMP antagonist, ectodin, integrating BMP, FGF, and SHH signals from the tooth enamel knot
Ectodin integrates BMP, SHH, and FGF signals in developing ectodermal organs.
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 TNF superfamily in skin appendage development
TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.
research Molecular biology of hair morphogenesis: Development and cycling
Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.
research Scratching the surface of skin development
The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.
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 Dynamic Signals for Hair Follicle Development and Regeneration
Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.
research Signaling Involved in Hair Follicle Morphogenesis and Development
The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.
research Conditional Disruption of Hedgehog Signaling Pathway Defines its Critical Role in Hair Development and Regeneration
The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.
research Transcriptome analysis reveals the genetic basis underlying the development of skin appendages and immunity in hedgehog (Atelerix albiventris)
Genes related to keratin, skin cell differentiation, and immune functions are key in hedgehog skin and spine development.
research Transcriptome analysis reveals the genetic basis underlying the development of skin appendages and immunity in hedgehog (Atelerix albiventris)

research Laminin-511 is an epithelial message promoting dermal papilla development and function during early hair morphogenesis
Laminin-511 is crucial for early hair growth and maintaining important hair development signals.
research Comprehensive molecular and cellular studies suggest avian scutate scales are secondarily derived from feathers, and more distant from reptilian scales
Bird scales evolved from feathers, not reptile scales.
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.
