    Construction of a High Fidelity Epidermis-on-a-Chip for Scalable In Vitro Irritation Evaluation

    Researchers grew and differentiated human keratinocytes within a microfluidic chip to construct an integrated epidermis-on-a-chip system, which was specially designed to integrate multi-culture units with integrated bubble removal structure.

    Abstract

    Quantitative Assessment of Sensitizing Potency Using a Dose–Response Adaptation of GARDskin

    Scientists analyzed dose–response relationships in the GARDskin assay to identify chemical-specific concentrations that were sufficient to induce a positive response in the assay.

    Abstract

    Calcium Silicate Accelerates Cutaneous Wound Healing with Enhanced Re-Epithelialization through EGF/EGFR/ERK-Mediated Promotion of Epidermal Stem Cell Function

    Researchers observed the effect of calcium silicate (CS) on human epidermal stem cells and investigated its possible mechanism. They explored the therapeutic effect of CS on wound healing and re-epithelialization.

    Identification of HMGCR as the Anticancer Target of Physapubenolide against Melanoma Cells by In Silico Target Prediction

    Scientists demonstrated that physapubenolide (PB) inhibited cell proliferation and migration in melanoma cells by inducing cell apoptosis. They explored the mechanism underlying the anticancer effects of PB through an in silico target prediction study.

    Host Responses to Implants Revealed by Intravital Microscopy

    The authors discuss how intravital microscopy can reveal regenerative and pathological responses to implants, including wound healing and graft integration, which depend on the time-controlled activation of macrophages and early neovascularization, and adverse reactions.
