Microscaffolds are porous 3D scaffolds with applications in high-throughput screening and cell therapy. Cells grow on, around and into the material, forming micro-islands of adherent cells that are effectively “micro-tissues in solution”.

Mimetix microscaffolds, made from the same polymer and with the same architecture as the scaffolds in our Mimetix well-plates, also contain iron particles so that they can be physically manipulated using magnets.

  • Reproducible 3-D culture environment
  • Applicable to any cell type
  • Movable: from vessels-to-well and well-to-well with magnetism
  • Scalable to any assay throughput
  • Seamless integration with screening and assay workflows

Recombinant HEK293 cells stably expressing CRE-luciferase (Promega) – monitors cyclic AMP (cAMP) levels in cells. Treatment with forskolin increases cAMP levels, which acts as a transcription factor and increases synthesis of luciferase. Experiment performed by Aurelia Bioscience.
Scaffold containing cells were defrosted and incubated in the Biowiggler for 24, 48 and 72 hrs prior to assay – only 72 hr data shown but data was consistent between these time points. Experiment by Aurelia Bioscience.

 

We developed microscaffolds in a collaborative project with Aurelia Bioscience. Project was supported by an InnovateUK/ NC3Rs grant.
