This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hair follicle's inner root sheath, suggesting a distinct functional role related to hair structure.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

In this study, researchers found that hair follicle stem cells activate an immune-modulatory program during wound healing, promoting Treg cell expansion and aiding skin repair, while deleting certain immune components impaired healing and increased inflammation in a mouse model.

This study identifies Activin A and follistatin as key regulators of hair cell differentiation in the mouse auditory sensory epithelium, influencing the timing and pattern of hair cell development.

This study found that disrupting the Sox21 gene in mice led to progressive hair loss and regrowth, identifying Sox21 as a key regulator of hair shaft cuticle differentiation.

This study found that keratin K80, structurally similar to hair keratins, is broadly expressed in various epithelial tissues and is involved in intermediate filament formation with multiple type I partners.

In this study, researchers found that simple hair clipping in mice induced dynamic plasticity and axogenesis in skin sensory axons, linked to follicular activation and HGF signaling.

In this study, bioengineered hair germ microspheres made from HME hydrogels promoted hair follicle regeneration in vivo, suggesting a promising approach for hair loss treatment.

This review discusses the role of toll-like receptors in cancer treatment, providing an overview of pre-clinical studies and clinical trials on TLR-targeted therapies and noting the challenges and future prospects.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study found that astaxanthin-loaded mucoadhesive patches effectively promoted recovery of oral premalignant lesions in vivo without the side effects seen with clinical tretinoin cream.

This study developed a biomimetic 3D skin model with vascularization potential to assess the impact of nano-zinc oxide (nano-ZnO), finding that nano-ZnO significantly influenced genes related to apoptosis, inflammation, and oxidative stress in skin cells.

This study reports that a new boron/nitrogen-doped carbon nano-onion-based delivery system for doxorubicin enhanced its uptake and anticancer effects in specific cancer cell types, while reducing cardiotoxicity in human heart cells.

The researchers reported that sulfated chitosan-containing sponges can modulate macrophage activity in diabetic wounds, reducing inflammation and promoting angiogenesis and tissue regeneration, which may enhance wound healing outcomes.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

In this study, noncultured autologous skin cells prepared using a tissue homogenizer significantly improved burn wound healing in rats compared to a control treatment.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

At the 21st Royan International Stem Cell Congress, researchers highlighted the growing integration in regenerative medicine, emphasizing advances in pluripotency, AI applications, and bioengineering for the development of accessible stem cell therapies.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This review discusses the anatomical and histological characteristics of facial fat compartments and reports no new clinical results, emphasizing a need for further research on their role in facial aging.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This study found that electrospun short fibrous sponges effectively mimic the 3D extracellular matrix, promoting tissue regeneration, angiogenesis, and wound healing in diabetic rats better than 2D fiber membranes.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This study found that gelatin sponges used as scaffolds in rats with deep wounds and periosteal defects enabled regeneration of diverse tissue types, including periosteum, skin, and appendages, highlighting the role of vascular niche formation.
