This review outlines the processes and potential of stem cells in regenerating skin, hair, and other tissues but presents no new experimental findings.

In this study, the researchers observed that MMP-2 and MMP-9 significantly fluctuated with the hair growth cycle in mice, suggesting their important role in hair development.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This study found that higher levels of the protein Flii were associated with enhanced hair follicle regeneration and longer hair fibers in a mouse model.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This research found that a biodegradable fibrous membrane incorporating fibroblast-derived ECM accelerated wound healing and improved neovascularization in a mouse model.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.

iNKT cells help develop and maintain healthy skin in young mice.

This study found that adipose-derived stem cell-conditioned media improved skin flap survival following ischemia/reperfusion injury in mice by increasing cell proliferation and the number of hair follicles, mediated by IL-6.

This study found diverse responses to the androgen dihydrotestosterone in rodent tissues, with most androgen-regulated processes being specific to particular tissues.

This review highlights the need for improved methods in cosmetic safety assessment, emphasizing the potential of engineered skin tissue for more effective detection and toxicological evaluation of cosmetic products, compared to traditional methods.

In this study, fetal stem cells were identified in adult human hair follicles long after childbirth, indicating potential for autologous therapies due to their pluripotent characteristics.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

In this study, epidermal stem cells were found to enhance blood vessel formation and support successful one-step transplantation of tissue-engineered skin in a rat model.

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 study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This review covers recent developments in materials for in vitro and in vivo stem cell manipulation, highlighting innovative substrate properties but does not report new experimental results.

This review discusses current challenges in selective androgen receptor modulator discovery and preclinical evaluation and reports no new results, emphasizing the need for basic research to improve safety and selectivity.

This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

This study suggests that cultured human hair follicle cells can potentially recreate epidermis and produce bioengineered hair follicles in a GMP cell factory for regenerative therapy in alopecia.

This article proposes several potential approaches for scar prevention and therapy, including anti-transforming growth factor-β strategies and tissue-engineered skin, but reports no new clinical results.

In a study on diabetic mice, researchers developed a protein-based hydrogel that leverages zinc ions and the natural compound phellopterin to promote cutaneous nerve regeneration, angiogenesis, and tissue remodeling in diabetic wounds, highlighting its potential for advanced wound therapy.

This review highlights promising recent advances in therapies for epidermolysis bullosa, including gene therapy and stem cell approaches, but reports no definitive cures and emphasizes the need for further research.
