マウス大動脈周囲脂肪組織からの間質血管分画由来前駆脂肪細胞の単離・培養・脂肪誘発

Executive Industry Relevance

Standardized isolation and adipogenic induction of stromal vascular fraction-derived preadipocytes from mouse periaortic adipose tissue (PVAT) enables mechanistic studies of adipogenesis and PVAT-vascular cell interactions. This capability supports predictive confidence in disease-relevant models for vascular biology and metabolic research. The protocol provides a reproducible foundation for early discovery and target validation in cardiometabolic R&D portfolios.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation
