シングルセル分解能でのエピゲノムおよび遺伝子発現プロファイリングのためのマウス心臓前駆細胞からの核分離(英語)

Executive Industry Relevance

Single-nucleus isolation from frozen mouse cardiac progenitor cells enables high-resolution epigenomic and transcriptomic profiling, overcoming the limitations of fresh tissue requirements. This capability supports robust investigation of cellular heterogeneity and regulatory mechanisms in heart development, directly impacting early discovery and target validation for congenital heart disease. Flexible sample handling and compatibility with dual-omics platforms enhance portfolio-wide experimental design and data integration.
