This review examines the role of nerves in regeneration across various species and discusses their importance as components in the progenitor cell niche, reporting no new clinical results.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

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

This study suggests that fibromodulin may regulate transforming growth factor-β activity during scar formation, influencing the transition from fetal scarless repair to adult scar-forming repair in rats.

This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This review synthesizes recent research on exosomes, highlighting their role as key modulators in regenerative outcomes and suggesting they may offer advantages over stem cell-based therapies in process and regulation.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This review discusses the features of regulatory T cells and the modulation of Foxp3, emphasizing post-translational modifications' impact on Treg function but reports no new clinical results.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This review discusses the development of electrospun nanofibrous scaffolds for promoting angiogenesis in tissue engineering but notes that their clinical application beyond bone and skin repair is still limited.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This article reviews the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This systematic review suggests that current evidence does not support routinely discontinuing gender-affirming hormone treatments before surgery, especially testosterone and spironolactone, due to limited data on related perioperative risks.

In this review, the researchers detailed how the p63 transcription factor influences epithelial stem cell activities such as self-renewal, differentiation, and proliferation, highlighting the role of TAp63 and ΔNp63 isoforms in both normal tissue development and cancer pathogenesis.

In this study, tofacitinib treatment was associated with significant hair regrowth in two patients with alopecia universalis over eight months, with minimal adverse effects reported.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.
