Extracellular Matrix Remodelling: Obesity-Associated Adipose Stromal Cells Promote Breast Cancer Invasion through Direct Cell Contact and ECM Remodeling (Adv. Funct. Keywords: collagen; extracellular matrix remodeling; obesity; optical coherence tomography; tumor invasion EN collagen extracellular matrix remodeling obesity optical coherence tomography tumor invasion 1 1 1 11/27/20 20201125 NES 201125 In article number 1910650, Claudia Fischbach and co-workers combine collagen-embedded multicellular spheroids and advanced imaging to investigate the effect of adipose stromal cells (ASCs) on tumor cell invasion as a function of obesity. Obese ASCs increase collective tumor cell migration relative to lean ASCs by stimulating proteolytic and contractility-dependent collagen remode ling, providing insights into how obesity promotes breast cancer malignancy.
