This study found that certain chemotherapeutic agents, such as cyclophosphamide, disrupt feather formation and induce hair loss in mice by inhibiting cell proliferation through sonic hedgehog gene downregulation.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

This study demonstrated that a mechanical-chemical cascade involving dermal cell contraction and the activation of Piezo1 in epidermal cells is crucial for initiating interactions necessary for hair follicle regeneration in skin organoids.

This study found that the differential expression of α- and β-keratin genes in feathers may explain their morphological and structural diversity, highlighting the chicken as a model for studying keratin-related diseases.

In this study, WNT10A was identified as a key gene in the development and maturation of skin hair follicles in fetal Inner Mongolian cashmere goats.

This study found that low-passage exosomes from dermal papilla cells enhance hair follicle stem cell proliferation and that miR-218-5p may serve as a potential biomarker and therapeutic target for hair growth.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.
