Miniaturization of an Anoikis assay using non-adhesive micromolded hydrogels
Research Overview
Anoikis is apoptosis triggered by loss of attachment to matrix or other cells, and simulating those conditions in vitro has made controlled, efficient assays difficult to build.
This study developed a microscale method for analyzing and quantifying anoikis using micro-molded nonadhesive hydrogels, which isolate single unattached cells in an ordered array with controlled distribution. Cell distributions across multiple seeding densities were compared against a mathematical probability model, using normal human fibroblasts, umbilical vein endothelial cells, and other types.
