Organoid models – 3D culture


Lung organoids provide a model system to study processes of repair/regeneration of lung epithelium. Defective alveolar repair as observed in COPD can be recapitulated using this model.

Organoids of alveolar epithelial cells in co-culture with fibroblasts can be used to evaluate efficacy of investigational compounds on stem/progenitor cell functions in the lung. Progenitor cells are isolated based on established protocols and brought into co-culture with fibroblasts to mimic the epithelial/mesenchymal communication that is required to drive alveolar repair.

Organoids can be generated from cells of murine and human origin and co-cultured with healthy and diseased primary human fibroblasts to study disease-specific communication between cell types during lung repair.

  • Organoid number
  • Organoid size
  • Differentiation into mature type I and II cells using immunofluoresence
  • Gene expression patterns

Additional read-outs are available on request.

The impact of your investigational compound on organoid formation can be investigated. We have identified different processes in organoid formation, that can all be modulated by inhibition or stimulation of specific pathways.  These processes include initial progenitor cell division, subsequent proliferative expansion and thereafter differentiation towards alveolar and airway organoids. Treatment scheme can be discussed depending on the target of interest, as treatments can be added at the start of each phase or as fibroblast pre-treatment.

Furthermore, models using disease stimuli such as TGF-B, IL-1B, cigarette smoke extract and diesel can be discussed.
