In this study, researchers developed a method using stencils to create controlled stiffness gradients in alginate hydrogels, revealing that stiffer regions within the gels promote deeper invasion by breast cancer cells, facilitating the study of mechanosensitive cellular behaviors.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

This study found that nanoemulsions incorporating skin penetration enhancers significantly increased the permeation of minoxidil through human skin compared to aqueous control solutions.

This study found that polymeric nanoparticle suspensions can deliver poorly water-soluble drugs to hair follicles in animal models, suggesting a promising method for targeted topical treatments.

The tropical legume Sesbania rostrata can form nodules in waterlogged conditions using a different method that involves plant hormones and specific genes.

This study found that using short durations of heat with chemical penetration enhancers improved isotretinoin delivery to human skin, especially via the hair follicles.

This study found that alkali bromide solutions are absorbed into hair depending on salt activity, and the presence of the salt increases water absorption compared to normal conditions.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This study found that white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This review compares animal and human skin characteristics in in vitro permeation studies but reports no new results, highlighting variations and the need for better model correlations.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This review discusses the oral manifestations associated with hematologic conditions and nutritional deficiencies, without presenting new research results; it emphasizes the impact of blood disorders and vitamin deficiencies on oral health.

This study found that the sebum partition coefficient (K(sebum)) for some drugs differs from the stratum corneum partition coefficient (K(sc)), indicating its importance for targeted drug delivery into hair and sebaceous follicles.

This study found that excipients significantly influence the effectiveness of curcumin nanocrystals in dermal applications, enhancing or hindering hair follicle targeting and passive diffusion based on their selection.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This study found that nanostructured lipid carriers provided better skin-targeted delivery and drug loading for lidocaine than nanoethosomes, indicating improved local anesthetic efficacy in vitro.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

The study reported that combining the Follicular Closing Technique with the Franz diffusion cell is a valuable method for investigating follicular caffeine penetration in vitro, though kinetics differ from in vivo results.

This study found that camelina oil supplementation was comparable to flaxseed and canola oil in supporting skin and coat health and managing inflammation in dogs over 16 weeks.

This study found that electroosmotic flow through hair follicles significantly contributes to solution flow during iontophoresis in hairless mouse skin.

This study reports that among men, skin surface hydration and pH change with age, but transepidermal water loss and sebum production show less variation.

This study presented a new two-dimensional model that successfully predicts transdermal permeation of caffeine, highlighting the significant role of the follicular pathway in increasing systemic bioavailability.

This study found that drug transport through artificial sebum varies depending on the compound, suggesting that sebum-targeted delivery can be optimized by selecting compounds based on their distinct transport profiles in sebum versus skin.
