Culture Patch for Organ-on-a-Chip

This culture patch is a system of monolayer gelatin nanofibers deposited on a patterned PEGDA microframe, with an optional collagen/laminin membrane. Its structure and composition perfectly mimics the in-vivo extracellular matrix. This solution offers the possibility to recreate tissue organization, cell-cell interactions, extracellular matrix influence and physiological responses in a more in vivo-like environment.
Compatible with traditional culture dishes, multi-wells, Boyden chambers and advanced organ-on-a-chip platforms developed by MesoBioTech.

Culture patches are designed to mimic sophisticated cellular environments. Mechanically stable and biocompatible, these patches reproduce the in vivo conditions for epithelial and endothelial tissue organization.

Based on a honeycomb microframe in PEGDA that supports a monolayer nanofibers backbone in gelatin, these patches are also available with ultrathin artificial basement membrane (100 - 200 nm thickness) in collagen and laminin to improve your cell culture. This additional membrane can be used to improve the monolayer formation of epithelial cells, and is semi-permeable which can slow down considerably the diffusion of large size molecules.

Two patches are available:

  • PEGDA frame - gelatin nanofibers
  • PEGDA frame - gelatin nanofibers - collagen/laminin membrane

Content

1x Culture patch

The culture patch comes sterile and has to be stored in dry conditions, without direct exposition to the sunlight at room temperature (15-25 °C). 

To grow your own 3D cell culture, the patch can be simply placed in a Petri dish, multi-wells, Boyden chambers or directly in a compatible microfluidic chip (click here for more information on the Organ-on-Chip setup). At the end of your experiment, the patch can be removed from the device for further analyses (e.g. imaging, proteomics and genomics). 
  • Mammalian cell culture
  • Human Induced Pluripotent Stem Cells (hiPSC) culture and differentiation
  • Tissue formation
  • Organoids formation
  • Drug discovery

Integration of a culture patch into the modular microfluidic chip of Mesobiotech gives rise to an Organ-on-Chip model.

Different patches can be used to culture cells or to differentiate Human Induced Pluripotent Stem Cells (hiPSC) in dish or microplates in order to create your specific tissue patch (e.g. cardiac, neuron, etc). Then, the tissue patch (or other tissue culture inserts) can be integrated in the assembled Organ-on-Chip. Micro-chambers and micro-channels are patterned in both plastic plates of the chip to create two independent microfluidic systems: the upper and the lower chambers separated by the tissue patch. These two microfluidic chambers can be perfused with different culture mediaThus a tissue interface can be formed to mimic alveolar, stomach, intestine, kidney, liver, brain-blood, skin functions, etc.

A co-culture of two different cell types is possible as well. In order to seed the cells on both sides a coating of matrigel and collagen is needed. The ratio of the mix will be cell type dependent. 

  

Benefits:

  • In-vivo like extracellular matrix
  • Natural or synthetic biopolymers 
  • High porosity 
  • Easy handling 
  • Easy device integration
  • Compatible with conventional culture systems

    By changing the cell type, these patches can be used to create:

    • Neural or cardio-vascular networks-on-a-chip,
    • Gut-on-a-chip,
    • Liver-on-a-chip,
    • Skin-on-a-chip,
    • Lung-on-a-chip,
    • Mesenchymal stem cells (MSC) or bone marrow-on-a-chip,
    • ESC or iPSC-derived stem cells (ESC/iPSC)-on-a-chip.

    A significative example of application: Lung Alveolus modeling. By differentiating hiPSCs into epithelial and endothelial cells on the upper and lower sides of a culture patch, an alveolar tissue is obtained and can be integrated into the microfluidic chip to recapitulate the pulmonary physiological conditions. By injecting growth factors, nano-materials or drugs, it is possible to study the extravasation and translocation of the tested compounds at the alveolar epithelium level.
