In this study, FITC-labeled BSA nanocarriers delivered a model drug deeper into porcine ear skin hair follicles than the carriers themselves, as shown by confocal microscopy.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.

A new method improves the isolation of hair follicle cells for better hair growth research.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

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 found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This study found that salinity stress in Arabidopsis thaliana root hairs may inhibit hair extension through changes in the tip-focused Ca(2+) gradient, while cytosolic pH remains unaffected.

This study suggests that a tip-focused gradient of intracellular G-actin concentration at the apex is crucial for root hair growth, and maintaining this gradient requires high calcium levels at the root hair tips.

This study found that a data-driven model using XGBoost effectively predicts individualized responses to minoxidil for androgenetic alopecia, outperforming traditional methods in accuracy and reliability.

This study established a method using reversed-phase high performance liquid chromatography to determine finasteride concentration in hair cosmetics, showing a strong linear relationship with mass concentration and recoveries between 90.3% and 102.0%.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This research describes a process for producing caffeine nanocrystals, which may enhance skin penetration by accumulating in hair follicles and maintaining stability for two months, paving the way for in vivo testing.

This study developed a validated HPLC method for accurately estimating dutasteride and its related compounds in capsules, suitable for routine and stability sample analysis.

This study found that in a rat skin model, fat cells inhibited the proliferation of organoid hair follicle cells and fibroblasts but may have accelerated hair follicle cell differentiation.

This study demonstrated that combining amorphization and nanonization of drugs enhances both saturation solubility and dissolution rate, potentially offering therapeutic benefits for formulations like dermal applications.

This study reports that hair samples can be used to track chronic hormone levels, revealing stress, reproductive, and sodium regulation patterns in wildebeest related to environmental factors.

This study reports two cases of fatal metformin intoxication with hair concentrations significantly higher than those in subjects under treatment, marking the first use of hair analysis for such cases.

This study suggests that platelet-rich plasma's high levels of growth factors may be limited in promoting bone regeneration due to the concurrent release of Dickkopf-1, which inhibits osteogenesis.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

Researchers developed a quick and sensitive way to measure finasteride in blood using a small sample size.

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.

Tissue stiffness affects sweat gland development by guiding cell differentiation through specific signals.

This study created a Wnt3a protein gradient using Multiphoton Microfabrication technology, which improved hair-inductive properties in mouse and human hair dermal papilla cells, suggesting potential applications in hair regeneration research and drug screening.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This article discusses various skin pattern formations, their molecular mechanisms, and highlights the need for further understanding to connect molecular biology with organism phenotypes, without providing new clinical findings.

This study identified Activin A and follistatin as key regulators of hair cell differentiation in the mammalian auditory sensory epithelium, with Activin A signaling influencing the timing and pattern of cell differentiation.
