简介：
Overview
This article presents a protocol for isolating whole, intact mouse mammary glands to study extracellular matrix (ECM) expression and ductal morphology. The method enables researchers to analyze histological presentations of mammary tissue ex-vivo, providing insights into tumor biology.
Key Study Components
Area of Science
- Neuroscience
- Biology
- Histology
Background
- Understanding ECM expression is crucial for studying mammary gland biology.
- The protocol aids in investigating ductal morphology in both healthy and diseased states.
- It addresses key questions regarding stromal remodeling in tumors.
- Utilizing nulliparous mice allows for controlled studies of mammary tissue.
Purpose of Study
- To facilitate the analysis of mammary tissue from intact glands.
- To characterize protein expression and ductal architecture.
- To provide a reliable method for studying mammary gland pathology.
Methods Used
- Harvesting mammary glands from 8-10 week old female nulliparous mice.
- Fixation in neutral buffered formalin.
- Sectioning and staining using immunohistochemistry for ECM proteins.
- Pinning carcasses and using ethanol for sterilization during the procedure.
Main Results
- Successful isolation of intact mammary glands for analysis.
