Modelo in vitro para el estudio de la diferenciación y los cambios de las células epiteliales de las vías respiratorias murinas estimuladas con extracto de humo de cigarrillo

Executive Industry Relevance

Establishing an in vitro model using primary murine airway epithelial cells exposed to cigarette smoke extract (CSE) enables mechanistic de-risking of airway remodeling and differentiation relevant to COPD pathogenesis. This system provides predictive confidence for early-stage target validation and supports translational continuity by closely mimicking in vivo airway responses to chronic smoke exposure. The model's multi-omics outputs inform portfolio decisions on respiratory disease targets and pathway prioritization.
