The National Eye Institute (NEI), part of the National Institutes of Health, is seeking ideas for how to develop advances in vitro 3-D human retina organoid models. The goal of the challenge is to turn innovative ideas into concrete concepts for the development of a 3-D system that models the cellular organization and function of the human retina. Full description and details of this prize competition are defined on NEI’s challenge details page.
NEI is seeking innovative solutions to achieve significant advances over currently available protocols to grow retina organoids. As solvers address the evaluation criteria outlined below, they should state how and why they expect their proposed new methods or changes/additions to existing methods will improve aspects of retina organoids. Solutions must outline ideas to produce 3-D retina organoids that:
- Are generated from human cells (derived from iPSC, federally approved ESC, multipotent cells, or adult cells subjected to a combination of transdifferentiation/reprogramming methods);
- Are physiologically and morphologically relevant to normal or disease state; and
- Consist of the major retina cell types and represent their biological functions and interplay.
Solutions that propose to grow cells in 2-D culture using a tissue-on-a-chip system are not of interest for this Challenge. However, creative approaches that incorporate use of microfluidics or perfusion to enhance culture of 3-D organoids are encouraged.
Cell Type, Structure, Viability, and Function - 50%
• Cell Types: What aspects of protocol ensure that all five neuronal retina cell types (photoreceptors, bipolar cells, ganglion cells, horizontal cells, and amacrine cells) will be produced on included? Will other cell types be generated or included? If the method eliminates a cell type, justify why it is not included (i.e. the disease being modelled lacks the specific cell type).
• Structure: What approach (e.g., self-organization or bioengineering with scaffolds, bioprinting, and/or a microfluidic apparatus) is proposed to achieve 3-D assembly? What aspects of the protocol ensure that 3-D organoids will be properly oriented and have layers recapitulating a laminated retina?
• Viability: Does the protocol incorporate new procedural steps or technologies that aim to increase duration of viability as compared to current protocols?
• Functional characterization of cell types: Does the solution incorporate novel steps or technologies that may enable all cell types to remain functional through the latest viable timepoint?
Robustness and Reproducibility - 25%
• Is the protocol sufficiently clear and detailed to facilitate inter/intra-laboratory utility and reproducibility? What other resources will be developed to facilitate transferability?
Scientific applications and uses for models - biology/disease modeling or high content screening - 25%
• What aspects of the protocol are in place to improve faithful recapitulation of the biological complexity?
• How will this recapitulation be validated?
• How will viability be tested, and how is the disease state expected to affect viability?
High content screening
• How will the proposed model’s amenability to high content screening be enhanced? How will this be tested?
• How will the model’s ability to recapitulate known retina toxicities be tested?
• What methods will be used to mass-produce the proposed model?
