Abstract Background Interactions between cancer cells and stroma are critical for growth and invasiveness of epithelial tumors. The biochemical mechanisms behind tumor-stromal interactions leading to increased invasiveness and metastasis are mostly unknown. The goal of this study was to analyze the direct effects of staged stroma-derived extracellular matrices on breast cancer cell be... https://www.spidertattooz.com/OPI-GelColor-Magnet-Tool-Mauvnetic-Poles-0-5-oz-p21159/
