    Wound Infiltrating Adipocytes Are Not Myofibroblasts

    Using genetic lineage tracing and live imaging in explants and in wounded animals, the authors observed that injury induced a transient migratory state in adipocytes with vastly distinct cell migration patterns and behaviors from fibroblasts.

    FAM3C/ILEI Protein Is Elevated in Psoriatic Lesions and Triggers Psoriasiform Hyperproliferation in Mice

    Mechanistically, ILEI triggered Erk and Akt signaling, which then activated STAT3 via Ser727 phosphorylation. Keratinocyte-specific ILEI deletion ameliorated TPA-induced skin inflammation.

    Patient-Derived Melanoma Organoid Models Facilitate the Assessment of Immunotherapies

    Researchers reported two different methods for generating melanoma patient-derived organoids, one which was embedded in collagen gel, and the other which was inlaid in Matrigel.

    Single-Cell Transcriptomics of Human-Skin-Equivalent Organoids

    By combining differential gene expression, pseudotime analyses, and spatial localization, scientists reconstructed human-skin-equivalent organoid cultures keratinocyte differentiation trajectories that recapitulated known in vivo epidermal differentiation pathways.

    In Vitro Effects of Undifferentiated Callus Extracts from Plantago major L, Rhodiola rosea L and Silybum marianum L in Normal and Malignant Human Skin Cells

    The anti-inflammatory and antioxidant activity of undifferentiated callus extracts from Plantago major L, Rhodiola rosea L, and Silybum marianum L was investigated both in normal and malignant skin cells.

    MicroRNA-205 Promotes Hair Regeneration by Modulating Mechanical Properties of Hair Follicle Stem Cells

    The authors showed that hair follicle stem cells in the bulge were stiff with high actomyosin contractility and resistance to size change, whereas hair germ progenitors were soft and periodically enlarged and contracted during quiescence

    mTORC1 Activity Negatively Regulates Human Hair Follicle Growth and Pigmentation

    Investigators used healthy, organ-cultured human scalp hair follicles to interrogate the role of mTORC1 in a prototypic human (mini-)organ.

    CCN1 Is Predominantly Elevated in Human Skin Dermis by Solar-Simulated Ultraviolet Irradiation and Accumulated in Dermal Extracellular Matrix

    Researchers explored the functionality of the matrix-bound CCN1 by culturing dermal fibroblasts on an acellular matrix plate that was enriched with a high concentration of CCN1.

    AbstractGraphical Abstract

    A Comprehensive Signature Based on Endoplasmic Reticulum Stress-Related Genes in Predicting Prognosis and Immunotherapy Response in Melanoma

    Scientists validated that silencing the expression of RAC1 could restrain the proliferation and migration, promote apoptosis, as well as increase the expression of PD-1/PD-L1 and CTLA4 in melanoma cells.

    Cooperation of TGF-β and FGF Signaling Pathways in Skin Development

    Scientists provide evidence of the role of TGF-β and fibroblast growth factor (FGF) signaling pathways in the development of different skin layers, especially the disparate dermis of different body regions.

    Chemokines As Possible Therapeutic Targets in Metastatic Melanoma

    The authors focus on the role of chemokines in melanoma and possible therapeutic strategies to alter chemokine activation and subsequently inhibit the activation of signaling cascades that may promote metastasis.
