Dissection, traitement histologique et analyse de l’expression génique du tissu adipeux brun supraclaviculaire murin

Overview

This study provides a detailed protocol for the dissection of supraclavicular brown adipose tissue (scBAT) from mice, which is deemed a valuable model for analyzing brown fat due to its anatomical similarities to human brown adipose tissue. The focus is on improving accessibility to scBAT research through precise dissection and subsequent histological and gene expression analyses.
