Isolation of Myofibroblasts from Mouse and Human Esophagus

Executive Industry Relevance

Reliable isolation and characterization of primary esophageal myofibroblasts enables disease-relevant modeling of stromal-epithelial interactions, a critical inflection point for target validation in fibrosis and tissue remodeling research. This protocol supports predictive confidence in early discovery by providing primary cell systems that closely reflect in vivo biology, reducing mechanistic ambiguity compared to immortalized lines. Consistent generation of pure stromal cultures facilitates cross-study and cross-condition comparisons, enhancing translational continuity across the R&D pipeline.
