    Two-Dimensional Biodegradable Black Phosphorus Nanosheets Promote Large Full-Thickness Wound Healing through In Situ Regeneration Therapy

    To investigate whether black phosphorus nanosheets have positive bio-effects on in situ skin repair, the authors verified black phosphorus nanosheets’ positive effects on angiogenic and anti-inflammatory abilities in vitro.

    Tenascin-C Expressing Touch Dome Keratinocytes Exhibit Characteristics of All Epidermal Lineages

    ScRNA-seq identified a specific touch dome keratinocyte marker, Tenascin-C (TNC). Lineage tracing of Tnc-expressing touch dome keratinocytes revealed that these cells maintained themselves as an autonomous epidermal compartment and gave rise to Merkel cells upon injury.

    Metformin and Adipose-Derived Stem Cell Combination Therapy Alleviates Radiation-Induced Skin Fibrosis in Mice

    Researchers conducted a comprehensive study to assess the effectiveness of metformin and adipose-derived stem cells, whether autologous or allogeneic, individually or in combination therapy, in mitigating radiation-induced skin fibrosis.

    Exosomal miR-4645-5p from Hypoxic Bone Marrow Mesenchymal Stem Cells Facilitates Diabetic Wound Healing by Restoring Keratinocyte Autophagy

    The experiments used human bone marrow mesenchymal stem cells from the American Type Culture Collection, an in vivo mouse model of diabetes to assess wound healing, as well as the human keratinocyte HaCaT cell line.

    Cell State Dependent Effects of Bmal1 on Melanoma Immunity and Tumorigenicity

    The authors showed that Bmal1 has a context-dependent role in mouse melanoma tumor growth. Loss of Bmal1 in YUMM2.1 or B16-F10 melanoma cells eliminated clock function and diminished hypoxic gene expression and tumorigenesis.

    Multiscale Spatial Mapping of Cell Populations Across Anatomical Sites in Healthy Human Skin and Basal Cell Carcinoma

    Investigators reported a comprehensive spatial atlas of adult human skin across different anatomical sites and basal cell carcinoma — the most common form of skin cancer—encompassing in vivo optical coherence tomography, scRNAseq, global spatial transcriptomic profiling, and in situ sequencing.

    Multiomics Characterization of Pyroptosis in the Tumor Microenvironment and Therapeutic Relevance in Metastatic Melanoma

    Scientists presented a computational model, pyroptosis-related gene score, or PScore, to assess pyroptosis status. They applied PScore to 1388 melanoma samples in amn in-house cohort and eight other publicly available independent cohorts.

    Membranal Expression of Calreticulin Induced by Unfolded Protein Response in Melanocytes: A Mechanism Underlying Oxidative Stress-induced Autoimmunity in Vitiligo

    Investigators found that the protein kinase RNA-like ER kinase branch of unfolded protein response was confirmed to be responsible for the overexpression and membranal translocation of calreticulin in melanocytes under oxidative stress.

    EPA Scraps Plan to End Mammal Testing by 2035

    The US Environmental Protection Agency (EPA) has abandoned a controversial plan to phase out all use of mammals to test the safety of chemicals by 2035. The hard deadline—imposed in 2019 to accelerate a move toward nonanimal models such as computer programs and “organs on a chip”—made EPA unique among US federal agencies.
