Figure Lengend Snippet: (A) Immortalized monocytes were primed to macrophages by adding 30ng/mL PMA. The macrophages were then polarized in three ways: M0 (naïve) without PMA, M1 (proinflammatory) with 10ng/mL LPS, 5ng/mL IFN- γ , and 30ng/mL PMA, and M2 (anti-inflammatory) with 25ng/mL IL-4, 25ng/mL IL-13, 30ng/mL PMA. (B) Macrophages directly activated on collagen type 1 (Col1)-coated soft or stiff polyacrylamide (PA) gels. After macrophage activation, human mammary epithelial cells (MCF10A) were seeded into a monolayer atop the macrophages.
Article Snippet: Polyacrylamide precursor solutions were mixed by adjusting 40% acrylamide (Bio-Rad: 161-0142) and 2% bis-acrylamide (Bio-Rad: 161-0140).
