In this study, the authors found that applying hypobaric pressure to the skin significantly increases the transdermal permeation of large molecules by enhancing diffusion, despite the associated skin stretching and hair follicle enlargement not fully explaining this effect.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

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 suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

This study discovered that the lipid in human hair follicles is mainly located in the hair cuticle and keratinized inner root sheath, distinct from sebaceous and epidermal lipids, suggesting a potential role as a "hair barrier.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

In this study, researchers developed a composite electrospun dressing with fiber gradient changes that mimics skin's natural structure, demonstrating enhanced wound healing, collagen deposition, and reduced fibrosis and scarring in both in vitro and in vivo experiments.

In this study, elevated mRNA levels for serine-rich ultra high sulfur proteins were observed during active hair growth phases in mice, particularly in the forming hair structures and upper skin layers.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

In this study, researchers examined the skin of neonatal rabbits and found that most hair follicles were in the terminal stage, with hair shafts protruding through the epidermis, but noted the absence of sweat glands.

This study found that high-resolution laser speckle contrast imaging devices provide good reproducibility for assessing skin perfusion in mice but not for measuring haemoglobin oxygenation.

This study identified that in mice, sweat gland development is directed by mesenchymal signals that suppress SHH-production, while in humans, this occurs through a BMP spike in embryonic development.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

New findings on hair keratin, wound healing, and skin blistering were presented.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This review discusses the role of epidermal differentiation complex genes and epigenetic mechanisms in skin development and certain diseases, emphasizing their potential for improving drug development and delivery systems but provides no new experimental results.

ZPK helps skin cells mature and may affect skin health.

This study found that poly(adenosine diphosphate-ribose) synthesis in human skin varies by cell type and condition, with distinct patterns in psoriatic, cancerous, and normal tissues.

This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This case study reported promising hair regrowth in a child with morphea en coup de sabre using fractional CO2 laser-assisted exosome therapy, but further research is needed to validate these findings due to its single-subject design.

This study found that androgen receptor expression varied across different types of skin appendage tumors, with specific expression patterns noted in sebaceous and sweat gland tumors but absent in hair follicle tumors.

This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.
