iPSC 유래 전구체 세포를 이용한 혈액-뇌 장벽 칩 생성

Executive Industry Relevance

This microfluidic blood-brain barrier model enables mechanistic de-risking of CNS-targeted therapeutics by providing a human-relevant system to evaluate barrier permeability and target engagement. It supports predictive confidence in lead identification by simulating physiological cell-cell interactions critical for drug transport studies. The platform addresses a key discovery inflection point where inadequate barrier models contribute to late-stage attrition in neurotherapeutics development.
