Collective migration in tissues

The Minisymposium on “Cell Migration in Tissues” focused on analysis of dynamic collective cell migration in several model systems and was cochaired by Alissa M. Weaver (Vanderbilt University Medical Center) and Celeste M. Nelson (Princeton University). The program highlighted both the physical forces exerted during migration and the signaling pathways involved in the process. Celeste Nelson (P...

Silk Film Topography Directs Collective Epithelial Cell Migration

The following study provides new insight into how surface topography dictates directed collective epithelial cell sheet growth through the guidance of individual cell movement. Collective cell behavior of migrating human corneal limbal-epithelial cell sheets were studied on highly biocompatible flat and micro-patterned silk film surfaces. The silk film edge topography guided the migratory direc...

3D Surface Topography from Intensity Images

This paper demonstrates how a new shape from shading scheme can be used to extract topographic information from 2D intensity imagery. The shape-from-shading scheme has two novel ingredients. Firstly, it uses a geometric update procedure which allows the image irradiance equation to be satisfied as a hard-constraint. This not only improves the data-closeness of the recovered needle-map, but also...

Engineered tissues to quantify collective cell migration during morphogenesis.

Renal development is a complex process involving the dynamic interplay of over 25 different cell types. One distinct step in this process is the formation of the ureteric tree, which develops from the repeated branching of the ureteric bud. During branching of the ureteric bud, cells migrate collectively in unison to form the complex structure of the tree. Here, we present a microlithography-ba...

Characterization of 3D surface topography in 5-axis milling

Within the context of 5-axis free-form machining, CAM software offers various ways of toolpath generation, depending on the geometry of the surface to be machined. Therefore, as the manufactured surface quality results from the choice of the machining strategy and machining parameters, the prediction of surface roughness in function of the machining conditions is an important issue in 5-axis ma...
