    Abstract

    Cancer-Associated Fibroblast-Mediated Cellular Crosstalk Supports Hepatocellular Carcinoma Progression

    Scientists investigated the novel cellular crosstalk among carcinoma-associated fibroblasts, tumor cells, and tumor‐associated neutrophils during different stages of hepatocellular carcinoma pathogenesis.

    Stromal NRG1 in Luminal Breast Cancer Defines Pro-Fibrotic and Migratory Cancer-Associated Fibroblasts

    Researchers showed that phosphorylation and activation of HER3 in luminal breast cancer cells occurred in a paracrine manner and was mediated by NRG1 expressed by cancer-associated fibroblasts.

    The Extracellular Matrix Regulates Cortical Layer Dynamics and Cross-Columnar Frequency Integration in the Auditory Cortex

    To understand the laminar interaction dynamics after ECM digestion, scientists used time-domain conditional Granger causality measures to identify the increased drive of supragranular layers towards deeper infragranular layers.

    Collagen I Fibrous Substrates Modulate the Proliferation and Secretome of Estrogen Receptor-Positive Breast Tumor Cells in a Hormone-Restricted Microenvironment

    The impact of a type I collagen matrix orientation and fibrous architecture on cell proliferation and response to estrogen receptor therapy were examined using estrogen-dependent breast tumor cells cultured in a hormone-restricted environment.

    The ECM as a Driver of Heart Development and Repair

    Investigators discuss the spatiotemporal changes in ECM composition during cardiac development that support distinct aspects of heart morphogenesis. They highlight conserved requirements for specific ECM components in human cardiac development, and discuss emerging evidence of a central role for the ECM in promoting heart regeneration.
