research The regeneration blastema of lizards: an amniote model for the study of appendage replacement
Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.
research Dermo‐epidermal interactions in reptilian scales: Speculations on the evolution of scales, feathers, and hairs
Reptilian scales, feathers, and hairs evolved from changes in skin cell interactions.
research Organizational principles of integumentary organs: Maximizing variations for effective adaptation
Integumentary organs adapt and evolve for survival, with potential uses in regenerative medicine.
research Reptile scale paradigm: Evo-Devo, pattern formation and regeneration
Reptile scales help us understand the evolution of skin features like hair and feathers.
research Structural and Immunocytochemical Characterization of Keratinization in Vertebrate Epidermis and Epidermal Derivatives
Vertebrate skin evolved to be more specialized and complex, especially in land animals.
research Review: Evolution and diversification of corneous beta‐proteins, the characteristic epidermal proteins of reptiles and birds
Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.
research Distribution of keratin and associated proteins in the epidermis of monotreme, marsupial, and placental mammals
Monotreme and marsupial skin proteins show primitive features and species-specific differences compared to placental mammals.
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 Transcriptome analyses of reprogrammed feather / scale chimeric explants revealed co-expressed epithelial gene networks during organ specification
Key genes can rewire networks, changing skin appendage types.

BMP2 and BMP7 have opposite roles in feather formation.
research Convergent Evolution of Cysteine-Rich Keratins in Hard Skin Appendages of Terrestrial Vertebrates
Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.
research Immunolocalization of a Histidine-Rich Epidermal Differentiation Protein in the Chicken Supports the Hypothesis of an Evolutionary Developmental Link between the Embryonic Subperiderm and Feather Barbs and Barbules
A specific protein in chicken embryos links early skin layers to feather development.
research Comparative biology of tissue repair, regeneration and aging
The symposium concluded that understanding how different species repair tissue and how this changes with age can help advance regenerative medicine.
research Molecular evolution of HR, a gene that regulates the postnatal cycle of the hair follicle
Changes in the HR gene have influenced hair growth and may lead to hair loss conditions in humans.
research Sexually dimorphic sail feathers in the Mandarin duck as a model for lifelong developmental modulation
Mandarin duck sail feathers change with seasons due to hormones and genetic regulation.
research Molecular signaling in feather morphogenesis
Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.
research Module-based complexity formation: periodic patterning in feathers and hairs
The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.
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 Inductive Properties of Hair Follicle Cells
Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.
research Localisation of members of the notch system and the differentiation of vibrissa hair follicles: Receptors, ligands, and fringe modulators
Notch-related genes play a key role in the development and cycling of hair follicles.
research Cultured human and rat tooth papilla cells induce hair follicle regeneration and fiber growth
Tooth papilla cells can help regenerate hair follicles and grow hair.
research Cellular senescence in tissue repair: every cloud has a silver lining
Cell aging can be both good and bad for tissue repair.
research Transformation of amnion epithelium into skin and hair follicles
Mouse amnion can turn into skin and hair follicles with help from certain cells and factors.
research The regeneration of caudal epidermal specializations inLygodactylus picturatus keniensis (gekkonidae, Lacertilia)
Lizards can regrow their tail scales with the same structure, distribution, and gender-specific features as the original ones, and this unique ability is not seen in adult mammals.
research Insights into the role of the Wnt signaling pathway in the regeneration of animal model systems
The Wnt signaling pathway is crucial for regeneration and could help advance human medicine.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Gap junctions in Turing-type periodic feather pattern formation
Gap junctions help control feather pattern formation in chickens.
research ROBO4 deletion ameliorates PAF-mediated skin inflammation via regulating the mRNA translation efficiency of LPCAT1/LPCAT2 and the expression of PAF receptor
