This study found that IL-1α promotes hair follicle regeneration and stem cell activation in an age-dependent manner by modulating inflammatory cells and oxidative stress in mice.

This review discusses vitamin D and calcium signaling roles in epidermal stem cell processes essential for wound healing but reports no new experimental results, emphasizing their potential interdependent regulatory mechanisms.

This study observed that microneedling-induced microinjury promotes hair growth via a TNF-α, Wnt, and VEGF pathway, while blocking TNF-α inhibits this process.

This narrative piece considers how epigenetic factors may influence the processes of skin wound healing, including hair follicle formation, but it presents no new experimental results.

In this study, a new topical formulation containing amine-activated carboxymethyl chitosan and hydrolyzed extracellular matrix showed promising results in a mouse model by reducing oxidative stress, inflammation, and promoting hair regeneration, potentially offering an alternative treatment for inflammatory hair loss.

This study found that growth hormone significantly reduced radiation-induced skin damage in rats compared to radiation alone, suggesting potential for mitigating such effects in cancer patients.

This study found that zinc supplementation reduced the severity and delayed the onset of radiation-induced skin injury in rats, with the greatest protection observed at a dose of 10 mg/kg/day.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

This study found that a newly developed mouse ear punch model effectively demonstrated that radiation significantly delays wound healing and may be used to study combined radiation and wound injury mechanisms.

This study concluded that controlled micro-injury induces hair regeneration and vitiligo repigmentation in mice, potentially through the Wnt/β-catenin pathway.

This study found that follicular stem cells in hair follicles are more sensitive to the antiproliferative effects of glucocorticoids compared to basal keratinocytes due to incomplete desensitization.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

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 observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

This study indicates that transient Msx2 expression is critical for wound-induced hair follicle neogenesis, with distinct phases in the healing process essential for epidermal competence and hair regeneration.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This study found that increasing commensal bacterial load on the skin enhances wound-induced hair follicle neogenesis in mice, mediated through IL1R-MyD88 signaling pathways.

In this murine study, researchers found that topical treatment with Philippine stingless bee propolis increased folliculogenesis, epidermal thickness, and melanogenesis, but not hair length, potentially supporting hair follicle regeneration and melanocyte function in chemotherapy-induced alopecia models.

This review discusses the cutaneous side effects of chemotherapy, noting that they frequently involve changes to skin, hair, and nails, and reports no new results.

This study demonstrated in rodent models that artificial dermal template treatment can induce full-thickness skin regrowth including skin epidermis and adnexa without the need for autologous skin grafts.

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.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This study reported that apremilast treatment did not lead to sustained improvement in SALT scores for most patients with extensive and treatment-resistant alopecia areata.

This review discusses advances in understanding the mechanisms behind radiation-induced skin reactions, highlighting recent insights into the roles of stem cells and immune cells in injury mitigation and late carcinogenesis, as reported in the context of ionizing radiation exposure.

This study developed a new protocol to efficiently produce skin dermal stem cells from human induced pluripotent stem cells, which may aid in treating various skin disorders.

This study found that cultured foreskin is not suitable for studying H2A.J-related tissue changes during radiation-induced dermatitis due to existing high H2A.J expression and cytokine secretion even without irradiation.

This study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

This study found that topical application of recombinant human MG53 protein mitigated nitrogen mustard-induced skin injuries in mice by preserving epidermal integrity and hair follicle structure.
