Executive Industry Relevance

Quantitative assessment of intermuscular adipose tissue (IMAT) is a critical challenge in muscle disease research, impacting target validation and mechanistic de-risking in early discovery. The decellularization-based protocol enables comprehensive, reproducible quantification of fatty infiltration in skeletal muscle, overcoming limitations of imaging and histology in small animal models. This capability supports predictive confidence in muscle-adipose crosstalk studies and informs risk-adjusted portfolio decisions for metabolic and neuromuscular disease programs.
