Growing interest in phenotypic screening, together with evidence that the drug response of cells grown in three-dimensional (3D) structures more closely resembles in vivo activity, has made high throughput, 3D fluorescence imaging an attractive screening option for drug discovery. However, creating 3D spheroids compatible with high content screening can be a difficult and expensive process.
BIOMIMESYS® is a range of patented hyaluronic acid scaffolds for 3D cell culture. They are made of RGDS- and galactosaminegrafted hyaluronic acid, using an adipic acid dihydrazide crosslinker and extracellular matrix proteins (eg. type I, IV or VI collagen) to accurately mimic the in vivo extracellular environment. BIOMIMESYS® is suitable for automated testing thanks to the uniform thickness of the scaffold – around 650 μm – with an average porosity of 100 to 200 μm
This application note describes a straightforward workflow for 3D cell seeding and spheroid formation using HCS Pharma’s BIOMIMESYS® plates in combination with INTEGRA’s VIAFLO 96/384 pipetting system. This process ensures rapid, controllable and reproducible 3D cell cultures, providing researchers with a highly efficient method to produce physiologically-relevant cellular models in a high throughput format.
