This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This study developed a rapid method to extract proteins from human hair, revealing phosphorylation on serine and threonine residues in alpha-keratins and matrix proteins.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

In this case report, researchers identified Arthroderma vanbreuseghemii as the cause of a familial fungal infection, which was successfully treated with itraconazole and topical terbinafine cream.

In a clinical observation study, researchers documented a case of total alopecia in an 11-year-old child, highlighting a potential link to genetic conditions such as autoimmune polyendocrinopathy candidiasis-ectodermal dystrophy (APECED syndrome) requiring further genetic and serological testing to verify the diagnosis.

Pax9 is crucial for proper tongue surface development and preventing skin-like changes.

This study found that a hair conditioner using peptides from Pneumatophorus japonicus heads improved damaged hair's structure, gloss, and smoothness more effectively than a commercial wheat protein conditioner by increasing amino acid content and interacting with hair keratin.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review investigates how the chirality of peptides affects their ability to form hydrogels, comparing the structural and mechanical properties of hydrogels made from homochiral and heterochiral peptides, and discussing their potential biological applications.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

Retinoic acid causes gland formation instead of hair in mouse skin by altering epidermal and dermal interactions.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

In this study, altering the photoperiod in goats increased hormone concentrations and improved hair follicle development and skin antioxidant capacity, suggesting that short photoperiods may create favorable conditions for cashmere growth.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.
