脱細胞化マウス肺と初代ヒト内皮細胞を用いた生体工学的肺移植

Executive Industry Relevance

Bioengineered lung transplantation using decellularized mouse lungs and primary human endothelial cells addresses a critical bottleneck in organ bioengineering: scalable, cost-effective experimental platforms for early-stage protocol optimization. This approach enables rapid, resource-efficient hypothesis testing for cell integration and scaffold compatibility, directly impacting target validation and mechanistic de-risking in regenerative medicine pipelines. The platform's flexibility supports iterative discovery and portfolio triage for cell therapy and organ replacement strategies.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables systematic interrogation of cell-scaffold compatibility and integration in a controlled, scalable system.
• Supports biological de-risking by allowing direct comparison of multiple cell types and recellularization conditions.
• Facilitates predictive confidence in cell selection and protocol reproducibility for downstream translation.

Screening & Assay Development

• Provides a standardized, reproducible mouse-scale platform for evaluating recellularization efficiency and tissue viability.
• Enables quantitative assessment of cell distribution and network formation using histological and molecular readouts.
• Supports assay scalability and platform reuse for iterative optimization of cell sourcing and perfusion parameters.

Translational & Preclinical Research

• Allows modeling of human cell behavior in three-dimensional, organ-scale environments relevant to disease and transplantation.
• Supports continuity from discovery through preclinical validation by enabling patient-derived or genetically modified cell testing.
• Provides a framework for risk-adjusted advancement decisions prior to scaling to larger animal models.
