In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

In this study, cultured skin equivalents with ovine hair follicle dermal papillae grafted onto nude mice developed follicle-like structures, suggesting a potential model for studying hair follicle development.

This study found that excess vitamin A in organ cultures of mouse embryos led to significant changes in epidermis and hair follicles, altering morphogenesis and polysaccharide distribution.

This study successfully developed and characterized a monospecific monoclonal antibody, LHTric-1, that specifically localizes to the pre-cortical region of the hair follicle and can aid research on hair and nail formation.

This study found that during amelogenesis in Msx2 null mice, a dysfunctional enamel organ developed due to abnormal epithelial transformation and lacked proper enamel formation.

This study describes unique anatomical characteristics of the skin and hair structures in the silver marmoset, including features such as thin epidermis, specialized nerve end-organs, and distinctive gland compositions.

This study sequenced a related gene to KRT2.9 called KRT2.13, which encodes a type II keratin protein not expressed in the hair follicle, and found significant sequence homology suggesting possible gene conversion or conservation of functional sequences.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

This case report describes a 62-year-old man with psoriasis who developed a unique nail abnormality after two months of treatment with the oral retinoid etretinate, alongside hair thinning and cheilitis.

KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

This study found that weakened anchorage of hair shafts, associated with the abnormal expression of 14-3-3σ, may contribute to alopecia in Er/+ mice.

This study investigates calcium and phosphorus accumulations in the hair of mummies from the Taklamakan desert and debates their exogenous or endogenous origin.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study used electron microscopy to characterize tissues on telogen hair roots, finding that tissue quality, including nucleated and nonnucleated epithelial cells, may play a crucial role in DNA typing for forensic analysis.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

This study identified various cell types in the canine claw, showing complex mechanisms of cellular differentiation similar to mammalian hair and human nails.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

This article reviews gaps in our understanding of molecular events in hair follicle growth, focusing on keratin synthesis and protein oxidation, but reports no new findings.

This review explores the immunological aspects of epidermal differentiation in loricrin knockout mice, offering insights into keratinization and potential intrinsic factors affecting immune function, but provides no new clinical findings.

The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This case report describes an 8 cm giant pilomatricoma on a 67-year-old man's scalp, revealing distinct transcriptional patterns related to hair follicle factors and keratin through spatial gene expression analysis.

The researchers developed a technique for processing and staining free hair samples using paraffin embedded blocks, revealing that routine staining does not color the enucleated cuticle, while the cortex and medulla show distinct colorations when stained.
