生理的サイズのマイクロ流体培養装置における上皮細胞単層の作製と構造評価

Executive Industry Relevance

Establishing uniform epithelial cell monolayers in physiologically relevant microfluidic devices is critical for predictive modeling of lung barrier function and injury mechanisms. This protocol enables quantitative and qualitative assessment of monolayer integrity, supporting early-stage target validation and mechanistic de-risking in respiratory disease research. Reliable monolayer evaluation underpins translational continuity from discovery through preclinical model development for conditions such as ARDS and VILI.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables rigorous assessment of epithelial barrier formation in microphysiological systems.
• Supports mechanistic de-risking by confirming monolayer uniformity prior to functional assays.
