    Exercise-Induced Piezoelectric Stimulation for Cartilage Regeneration in Rabbits

    Scientists demonstrated that a biodegradable piezoelectric poly(L-lactic acid) nanofiber scaffold under applied force or joint load could act as a battery-less electrical stimulator to promote chondrogenesis and cartilage regeneration.

    Quantification of T and B Cell Immune Receptor Distribution Diversity Characterizes Immune Cell Infiltration and Lymphocyte Heterogeneity in Clear Cell Renal Cell Carcinoma

    Investigators quantified tumor infiltration across two distinct clear cell renal cell carcinoma patient tumor cohorts using complementarity determining region-3 (CDR3) sequence recovery counts in tumor-infiltrating lymphocytes and a generalized diversity index for CDR3 sequence distributions.

    Regeneration of Collagen Fibrils at the Papillary Dermis by Reconstructing Basement Membrane at the Dermal–Epidermal Junction

    Researchers suggested that reconstructing the basement membrane promoted secretion of platelet-derived growth factor consisting of two B subunits by epidermal keratinocytes, leading to increased collagen expression at the papillary dermis.

    Abstract

    Cell-Adhesive Gels Made of Sacran/Collagen Complexes

    Polymer complex gels of sacran with cell-compatible proteins and collagen were prepared. Complex gels of sacran and collagen were observed using fluorescence and polarized microscopes, which indicated the complexation characteristics of sacran and collagen, as well as their partial orientation.
