This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

This study observed distinct sex differences in hair growth cycles and regeneration in C3H/He mice, noting that females regenerated hair faster after adhesive material application, whereas males were more reliant on macrophage activity for this process.

In this case study, an 11-month-old cat developed non-pruritic hair loss in the dorso-lumbar area after a road accident, with histopathological examination revealing post-traumatic changes such as absence of hair follicles and pyogranulomas.

Innovative methods are reducing animal testing and improving biomedical research.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

In this study, researchers identified IL18R+ thymus-resident regulatory T cells in mice, demonstrating their unique molecular features and resistance to age- and stress-induced thymus involution, highlighting IL18 signaling's role in Treg migration and retention.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study found that nociplastic type pain is a complex and heritable trait, with significant genetic overlap with multisite chronic pain and some connection to rheumatoid arthritis and a neuropathic pain phenotype.

This study identified robust susceptibility genes and potential drug candidates for male-pattern baldness, providing insights into the condition's molecular mechanisms.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

In this study, Alox15 knockout mice exhibited disrupted skin integrity and increased inflammation, suggesting that Alox15-mediated resolvin D2 production is crucial for maintaining skin homeostasis by suppressing inflammation.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

This analysis found that mesenchymal stem cell-derived exosomes show potential as a safe and effective treatment for various skin and subcutaneous tissue diseases.

This study observed that in the bald scalps of male patients with androgenetic alopecia, there was a significant downregulation of the PPAR signaling pathway, suggesting reduced adipogenesis potentially influencing hair cycling processes.

In this first-in-human study, BLZ-100, an intraoperative fluorescent imaging agent, was administered to 21 patients before skin cancer surgery and was found to be well tolerated without serious adverse effects, suggesting its potential to help distinguish cancerous from non-cancerous tissue based on fluorescence.

This study found that dermal papilla-like tissue reconstructed using canine adipose-derived mesenchymal stem cells closely resembles actual canine dermal papilla cells in both morphology and molecular characteristics.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study identified 1965 different metabolites in various tissues of *Oresitrophe rupifraga* Bunge using a targeted metabolomics approach and found significant metabolic differences between its aboveground and underground parts, providing insights into the plant's unique growth traits and potential cultivation and utilization.

In this review, extensive analysis using conditional mutant mice revealed that androgen and Wnt signals play crucial roles in the development and function of male external genitalia and erectile tissue, while also exploring various regulatory factors involved in their pathogenesis.

This study found that hMSC secretomes from umbilical cord Wharton's jelly had the most potent angiogenic effects, whereas those from adipose tissue demonstrated the weakest angiogenic potential.

This review discusses stem cell behavior, highlighting their plasticity in tissue repair and the impact of somatic mutations on clonal expansion in early cancer, but reports no new experimental results.

This study found that peribulbar lymphocytic infiltration can effectively differentiate between alopecia areata and androgenetic alopecia using T-cell infiltration patterns in skin tissue.

In this study, researchers successfully constructed a high-precision three-dimensional model of human skin dermis, revealing a detailed analysis of dermal porosity and pore diameter distribution, which can aid the development of biomimetic tissue-engineered skin.

This review discusses the applications of biopolymeric composites in controlled drug release, tissue engineering, and wound healing, but reports no new experimental results, highlighting the need for further development and analysis.

This study found that transplanting GFP transgenic tail skin onto wild-type mice leads to partial replacement of dermis, nerves, and blood vessels by recipient tissue after six months, while epidermis, hair follicles, and sebaceous glands persist from the graft.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

The researchers reported that several m6A-related genes, particularly IGF2BP3, were differentially expressed in keloid tissue compared to normal skin, indicating potential targets for understanding keloid pathogenesis and treatment.

This study identified genes potentially involved in the development and differentiation of skin appendages in Atelerix albiventris, noting significant enrichment of immune-related genes in hair-type tissues.

This study identified specific genes involved in radiation-induced fibrosis in skin, capsule, and muscle tissues of breast cancer patients, offering insights that may help improve mitigation strategies for these side effects.

This study used single-cell RNA sequencing to explore the cellular differences between small and large wound tissues during the hair follicle regeneration stage, revealing variations in keratinocyte subpopulations and extracellular matrix interactions associated with wound size.
