(1pt tоtаl) Reseаrchers hаve generated twо nоvel electrospun PLGA fibers. Fiber 1 had an average fiber diameter of 0.35 +/- 0.1 microns and 70% porosity. Fiber 2 had an average fiber diameter of 2.5 +/- 0.1 microns and 82% porosity. The researchers were interested in assessing inflammation/immune response. They performed an in vitro test first whereby they plated mature macrophages on the surface of the substrates and evaluated the number of total macrophages adherent on each substrate at 24hrs AND the production of tumor necrosis factor-α (TNF-α; a marker of pro-inflammatory macrophage activity) via ELISA. (0.25pts). The cell adhesion with the macrophages is presented below. State the results of this graphical data (0.25pts) The results from the ELISA assay are presented in the enclosed plot (including a positive and negative controls). State the results of this graphical data. (0.5pts) Summarize the data from the assays in part A and B relative to the substrate/fiber topographical properties.
