This study found that IBA-1-immunopositive macrophages in rat skin during wound healing show varied morphometric characteristics and peak in numbers at 2, 6, and 15 days post-injury.

This review discusses novel molecular techniques in skin appendage research and summarizes the distribution of key molecules, but it reports no new experimental results.

In this study, the introduction of autofibroblasts into ischemic wounds was found to be slightly less favorable for regenerative histogenesis compared to a dermal equivalent with heterofibroblasts, with minor differences in epidermis thickness, collagen fiber area, and blood vessel area.

This study found that activation of a mother's immune system during early pregnancy in mice led to transient alopecia in their offspring, highlighting a link between epidermal and dermal histogenesis disorders and alopecia.

In this animal study, the researchers found that DPP4 plays a crucial role in scar formation and wound-induced hair follicle neogenesis in mice, impacting regenerative repair.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

In this review, the authors discuss how understanding and co-regulating multiple signaling pathways could lead to effective regeneration of functional hair cells, highlighting current achievements and future approaches such as small molecule drugs and gene therapy for treating sensorineural hearing loss.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

In this study, murine follicular cell aggregates developed into hair-like structures in culture, which upon implantation into mice skin matured into complete hair follicles, suggesting potential for treating hair loss.

In this study, neonatal murine skin-derived cells transplanted using a mini-chamber method successfully produced robust and normal hair, contrasting with human scalp follicles which did not achieve follicle reconstruction.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

This review discusses the wound healing process and the factors contributing to abnormal scarring after thermal injuries, but it reports no new clinical results.

This review discusses various types of stem cells used in regenerative medicine, including adult stem cells and induced pluripotent stem cells (iPSCs), and evaluates them based on their embryonic tissue origins to explore new therapeutic approaches.

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.

Feathers become harder as they develop due to a change in keratin type.

This review discusses the development of Matrigel and its role in identifying thymosin beta 4 as a regenerative protein, without reporting new experimental findings.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This review discusses the expression patterns and biochemical roles of Msx and Dlx genes during development but does not present new research findings.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

In this study, the authors observed that cell-mediated immune mechanisms may be involved in the pathogenesis of benign follicular mucinosis, based on the cellular and immunological characteristics of two patient cases.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

This study observed significant clinical effects, such as hair loss and testicular changes, in common quail treated with the steroids IVF-C Inj and Diane-35, especially highlighting cyproterone acetate's impact on vital organs like the liver.

Burn scars form abnormally due to changes in wound healing, and more research is needed to improve treatments.
