This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

Laser treatment shows promise for hair growth, but needs further research.

This review discusses the role of the immune niche in hair follicle regeneration and its impact on different forms of alopecia, highlighting research gaps and potential therapeutic strategies.

This study found that 660 nm laser treatment and povidone iodine both eradicated Pseudomonas aeruginosa infection in mice wounds, with the laser enhancing healing, and the combination provided additive or synergistic healing benefits.

This article explores questions about dormant hematopoietic stem cells and suggests avenues for future research, but does not present new experimental results.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This study found that recombinant murine IL-36α increased the number of regenerated hair follicles and accelerated wound healing in a mouse model of wound-induced hair follicle neogenesis.

This study found that in a mouse model of Focal Dermal Hypoplasia, treatment with lithium carbonate improved skin disease symptoms compared to controls, though disease severity varied and posed interpretation challenges.

This study suggests that infiltrating M2 macrophages promote wound-induced hair neogenesis in mice by producing growth factors that activate the wnt signaling pathway during the late phase of wound healing.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

Laser therapy helped new hair grow in scarred skin for three patients.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

This case report describes an 80-year-old patient whose scalp wound healed by secondary intention, with unexpected hair regrowth observed at 180 days, suggesting hair neogenesis is possible even in older adults.

In this study, patients with androgenic alopecia who underwent 10 sessions of 1540-nm fractional erbium glass laser treatment over 5 months experienced significant improvements in hair density and thickness, with no major safety concerns reported.

This review discusses the roles of DNA methylation in skin development and regeneration, highlighting its impact on embryonic skin lineage, homeostasis, and potential therapeutic targets, but reports no new clinical results.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.

This review discusses the cellular and molecular changes involved in cutaneous wound re-epithelialization and EMT, highlighting their similarities and differences, but reports no new clinical results.

In this study, bovine testes hyaluronidase accelerated wound healing in vitro and in vivo by enhancing cellular proliferation, reepithelialization, and modulating inflammation in rat models.

This study found that hydrogen peroxide interfered with scarless healing in a murine fetal wound repair model, potentially by inducing transforming growth factor-beta1, which may contribute to increased fibrosis.

This study found that Teucrium polium L. subsp. geyrii Maire extract demonstrated a large safety margin in acute and subacute toxicity tests on mice and significantly enhanced wound healing in rats, especially with callus extract, by improving cell proliferation and wound contraction.

This study found that IL-6 knockout mice exhibited increased wound-induced hair neogenesis compared to wild-type mice, likely due to enhanced STAT3 activation facilitated by compensatory cytokine activity.

This study describes how manipulating the actin cytoskeleton, particularly through the gelsolin family proteins, may enhance regenerative healing in mammals, suggesting potential therapeutic pathways for improved wound repair.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.
