This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

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.

This study found that rubbing significantly increased skin permeation of caffeine but not rhododendrol, with the direction of rubbing playing a crucial role in caffeine's enhancement.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that in bovine skin, leptin and its receptor are expressed in the epidermis and hair follicles, suggesting a role in epidermis growth and hair follicle cycling through paracrine and autocrine mechanisms.

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

This study found that adipokines were expressed in the epidermis, hair follicles, sebocytes, apocrine glands, and vascular endothelium of normal canine skin, but not in the dermis or hypodermis.

This paper reviews several dermatological studies, including findings on hair growth, skin damage, bullous pemphigoid, and psoriasis treatments, and reports no new clinical results.

This study developed a new quantitative method to measure skin cell turnover in just 4 days, showing it can effectively differentiate skincare product performance and revealing that turnover slows with age but responds more to treatments as people get older.

This study suggests that microneedling may be an effective and less painful treatment for vitiligo, offering benefits over traditional needle injections, particularly in challenging-to-treat areas like the extremities or stubborn regions.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

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 the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

The study reports that the AVET system showed higher efficiency in transfecting cultured human keratinocytes compared to SuperFect and PrimeFector, with AVET reaching levels of enzyme activity similar to normal cells in keratinocytes from lamellar ichthyosis patients.

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 provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

This article discusses the disputed role of scalp micro-organisms in dandruff and notes that effective anti-dandruff treatments often have good antimicrobial activity, but it reports no new clinical results.

This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.

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.

This study found that melatonin enhanced whisker growth in vitro and identified MT1 receptor presence in the granular layer of mouse epidermis and the outer root sheath, suggesting potential for hair growth treatment.

This study found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.

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, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

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 demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

Vitamin D3 affects cell differentiation in specific skin areas.
