Sensitivity of Edge Detection Methods for Quantifying Cell Migration Assays

TL;DR: The modeling indicates that variations in the image threshold parameter correspond to a consistent variation in the local cell density, which means that varying the threshold parameter is equivalent to varying the location of the leading edge in the range of approximately 1–5% of the maximum cell density.

Are in vitro estimates of cell diffusivity and cell proliferation rate sensitive to assay geometry

TL;DR: In this article, the authors used a circular barrier assay to characterize the spreading of cell populations in two different geometries: a tumour-like geometry where a cell population spreads outwards into an open space and a wound-like geometrical geometry where the cell population moves inwards to close a void.

Sensitivity of edge detection methods for quantifying cellmigration assays

TL;DR: In this article, a suite of two-dimensional barrier assays describing the collective spreading of an initially-confined population of 3T3 fibroblast cells is presented and compared with a manual edge detection method where they systematically vary the detection threshold.

TL;DR: In this paper, the authors examined the sources of plastic strengthening in [0,0,1] epitaxial Cu/Ni multilayer thin films using measurements of in-plane lattice parameter and hardness (H) for films of different bilayer period (Λ) and Ni volume fraction (% Ni).
