This study reports that using nanogel and layer-by-layer self-assembly to encapsulate single dermal papilla cells can form cell spheroids that regenerate hair follicles successfully in a hair follicle regeneration model.

This study reports that transplantation of an ESCs-collagen-chitin biomimetic membrane leads to successful in situ skin regeneration, including hair follicle cell proliferation and formation of dermatoglyphs, in nude mice with full-thickness skin defects.

This study demonstrated that PEGDA hydrogel microwells successfully supported cell survival and proliferation while mimicking hair follicle architecture in vitro, suggesting a potential tool for hair follicle engineering.

This study investigated the use of dissolving microneedle patches to improve the skin-lightening effects of alpha-arbutin and resveratrol, finding that the patches enhanced intradermal delivery and slightly decreased the melanin index without affecting skin hydration or causing irritation over 24 hours.

This study found that the CXXC5 protein is overexpressed in diabetic foot ulcer tissues, suppressing wound healing, and that the small molecule KY19334 accelerated healing in diabetic mice by activating the Wnt/β-catenin pathway.

This study observed that dermal papilla cell aggregates showed increased viability and gene expression on softer 3D substrates, indicating the importance of substrate stiffness in cellular behavior.

This study concluded that hair-derived stem cells from older donors may offer a promising alternative for autologous corneal endothelial replacement, potentially benefitting patients of various age groups.

This study found that a new SIS-PEG sponge promoted rapid skin defect healing in mice and showed potential for reconstructing reconstituted skin with regenerated hair.

Finasteride negatively affects fish reproduction and gonadal development.

In this study, the researchers reported that while both propylene glycol and sodium lauryl sulfate enhanced finasteride's skin deposition, ethanol was the only effective enhancer of finasteride's permeation through the skin.

This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.

This study found that topical application of metformin significantly enhanced skin regeneration in mechanically stretched skin in rats, likely by boosting the proliferation of skin-derived stem cells.

In this review, the researchers explored the formulation and evaluation of a pure herbal shampoo using plant extracts, aiming to compare its physicochemical properties with synthetic and other herbal shampoos, and concluded that consumer expectation shifts towards safety and efficacy could enhance herbal shampoo popularity.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.

This study concluded that a new model of reconstructed human epidermis using keratinocytes from plucked hair follicles offers a less-invasive alternative to conventional skin-derived models for skin research.
