This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study identified candidate compounds from a natural-product library that may interact with the PIEZO1 and MLCK pathways, potentially countering a non-androgen cause of hair follicle miniaturization, all based on computer simulations; experimental validation is necessary.

This study demonstrates that Wnt signaling plays a crucial mechanoregulatory role in skin regeneration by influencing cellular responses to substrate rigidity, which promotes hair follicle regeneration in the wound-induced hair neogenesis model.

In this review, the authors emphasize that phenotypic heterogeneity in genetic systems and human diseases is influenced by stochastic fluctuation and network topology, proposing that ultrasensitivity and threshold effects explain this variability, which may inform strategies for preventing and treating genetic diseases.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

This study reports that localized Rho GTPase activity and ROS production play a critical role in polarized growth and movement in both migrating endothelial cells and developing plant root hairs.

This study examined how reactive oxygen species influence cell wall biomechanics in Arabidopsis thaliana root hairs, providing insights essential for understanding plant growth, stress responses, and potential agricultural applications.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

This study presents additional data suggesting that the absence of nerve endings in certain segments of human hair follicles influences the asymmetrical distribution of electrical charges, as indicated by no precipitation of Potassium Ferricyanide crystals.

The hydrogel helps heal diabetic wounds by combining antibacterial, antioxidant, and immune-boosting effects.

This study found that canonical Notch signaling inhibits Merkel cell specification during embryogenesis, while skin abrasions decrease Merkel cell number only in hairless mice.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

Using a vibrating device during injections can help reduce pain.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This review examines the design strategies for creating conductive hydrogels with adjustable properties for various biomedical applications, highlighting their potential for supporting cell growth, wound healing, drug delivery, tissue regeneration, and biosensing.

In this study, researchers developed an innovative wound healing patch combining electrical and chemical components, which effectively guided recovery in animal scald models by promoting collagen deposition and the regeneration of skin structures.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This study examined both human and mouse follicles, finding that cannabinoid and TRPV1 systems independently regulate hair follicle biological functions, impacting hair growth and development.

This study localized Merkel cells in human skin, finding them in the basal layer of glabrous skin at palms and soles, and in the interfollicular epidermis and isthmus region of hair follicles.

In this study, researchers developed a hierarchically engineered microreactor that effectively combats infected wounds by releasing antimicrobials at acidic sites, eradicating MRSA while avoiding resistance, and enhancing tissue repair through immune system modulation.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that Sonic hedgehog signaling is crucial for Merkel cell development around hair follicles in mice, with Polycomb repressive complex 2 loss causing ectopic Merkel cells across all hair types.

In this study, researchers found that using bioinspired nanovesicles derived from inflammation memory-activated epidermal stem cells effectively promoted healing in diabetic wounds by reprogramming neutrophils to an anti-inflammatory phenotype in both laboratory and animal models.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study found that Merkel cells in dogs are most numerous in sensory receptive areas like oral mucosa and facial skin, indicating a potential role in tactile sensation.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This review assesses the potential of smart dressings, engineered to respond to various stimuli, as advanced treatments for chronic inflammatory skin diseases by examining their activation mechanisms and proposing future developments like integrating AI and closed-loop monitoring for adaptive therapy.

This study reported the development of a pH-responsive microreactor that effectively targets infections by eradicating over 99.9% of MRSA and reprogramming the immune response to promote healing, achieving complete infection clearance and tissue regeneration in a 7-day period.
