Summary
This study by Dean, D.M. and Morgan, J.R was published in Cell Motility and the Cytoskeleton, 2009. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in developmental biology research.
Fibroblast elongation and dendritic extensions in constrained versus unconstrained microtissues
Research Overview
Cytoskeletal tension drives processes from germ-layer sorting in embryos to cell sorting in 3D microtissues — and it can be strong enough to tear complex-shaped microtissues apart. To study that failure directly, normal human fibroblasts underwent directed self-assembly in micro-molds designed to produce self-constraining microtissues.
As the cells contracted, the constrained microtissues narrowed, thinned, and ultimately failed at their midpoints. Adding small numbers of GFP-positive cells let the authors track movement and morphology, revealing that cells formed numerous dendritic extensions under tension compared with unconstrained microtissues.
