Różnicowanie i obrazowanie brązowych adipocytów z frakcji zrębowej naczyniowej tkanki tłuszczowej śródłopatkowej od nowonarodzonych myszy

Overview

This study provides a detailed protocol for the differentiation of preadipocytes into mature brown adipocytes using interscapular brown adipose tissue harvested from newborn mice. The differentiated cells display characteristic lipid accumulation, express key adipogenic markers, and exhibit mitochondrial adaptations indicative of thermogenic functionality.

Key Study Components

Research Area

• Adipocyte biology
• Obesity research
• Mechanisms of thermogenesis

Background

• Investigation of brown adipose tissue's role in energy metabolism
• Modeling conditions related to obesity and lipodystrophy
• Importance of preadipocyte differentiation for studying adipogenesis

Methods Used

• Immunofluorescence and transmission electron microscopy
• Interscapular brown adipose tissue from newborn mice
• Cell differentiation protocols and assays for mitochondrial characteristics

Main Results

• Successful differentiation of preadipocytes into mature adipocytes marked by lipid droplet accumulation
• Enhanced expression of adipogenic transcription factors and thermogenic markers on differentiation day seven
• Characterization of mitochondrial morphology changes associated with adipogenesis

Conclusions

• This protocol enables the reproducible study of brown adipocyte differentiation and functions.
• Relevance to understanding obesity and potential therapeutic targets.
