使用组织解离器从小鼠白色脂肪组织中半自动分离基质血管部分

Overview

This study focuses on the semi-automated isolation of the stromal vascular fraction (SVF) from murine adipose tissue, with the aim of obtaining preadipocytes and promoting adipocyte differentiation in vitro. A novel protocol utilizing a tissue dissociator for collagenase digestion is presented, which enhances reproducibility and reduces experimental variation.

Key Study Components

Research Area

• Adipocyte differentiation
• Energy expenditure in obesity treatments
• Murine models for metabolic research

Background

• Different functions of brown, beige, and white adipocytes
• Need for reproducible methods in adipocyte research
• Identification of critical transcription factors regulating differentiation

Methods Used

• Semi-automated isolation using collagenase digestion
• Murine adipose tissue
• Tissue dissociators and enzymatic assays

Main Results

• Improved methods for isolating SVF and differentiating adipocytes
• Successful differentiation demonstrated via Oil Red O staining and mRNA analysis
• Investigation into the effects of Rosiglitazone on brown fat-specific gene expression

Conclusions
