简介：
Overview
This protocol describes the isolation and culture of bone marrow-derived macrophages from mice. It aims to obtain high amounts of unstimulated macrophages that have never been exposed to tissue factors or cytokines.
Key Study Components
Area of Science
- Cell Biology
- Pathology
- Immunology
- Parasitology
Background
- Macrophages play a crucial role in the immune response.
- Isolation of these cells is essential for various research applications.
- Contamination can affect cell viability and results.
- Proper sterile techniques are necessary during the procedure.
Purpose of Study
- To isolate a large quantity of bone marrow-derived macrophages.
- To provide a reliable method for researchers studying macrophages.
- To ensure the cells are unstimulated and viable for experimentation.
Methods Used
- Bone marrow extraction from mice.
- Cell culture techniques to maintain macrophage viability.
- Use of a laminar flow biosafety cabinet to prevent contamination.
- Isolation procedures to obtain approximately 2 x 10^7 macrophages from a single animal.
Main Results
- Successful isolation of a high yield of macrophages.
- Cells remained unstimulated and viable for further research.
- Demonstrated the effectiveness of sterile techniques in cell culture.
- Provided a reproducible method for future studies on macrophages.
Conclusions
- The protocol is effective for isolating bone marrow-derived macrophages.
- High yields can significantly aid in various research fields.
- Maintaining sterility is crucial for cell viability.
What are bone marrow-derived macrophages?
Bone marrow-derived macrophages are immune cells that originate from bone marrow and play a key role in the immune response.
Why is it important to use unstimulated macrophages?
Unstimulated macrophages provide a baseline for studying their natural behavior without the influence of external factors.
What precautions should be taken during the isolation process?
Sterile techniques must be followed to prevent contamination and ensure cell viability.
How many macrophages can be isolated from a single mouse?
Approximately 2 x 10^7 macrophages can be obtained from a single animal using this protocol.
Who demonstrated this procedure?
The procedure was demonstrated by Izabela Aparecida de Souza, a Master degree student from the laboratory.
