简介：
Overview
This study presents a cost-effective method for purifying and expanding highly homogeneous bone marrow mesenchymal stem cells (BMSCs) from mice. The protocol not only simplifies the isolation process but also enhances the proliferation and differentiation capabilities of the obtained BMSCs, advancing preclinical research using mouse models.
Key Study Components

What are bone marrow mesenchymal stem cells?
They are multipotent stem cells found in bone marrow that can differentiate into various cell types and are pivotal in regenerative medicine.
How does this protocol improve upon previous methods?
It provides a more straightforward and low-cost approach, resulting in high yields of pure stem cells.
What is the significance of using a mouse model?
Mouse models are widely used in preclinical research, allowing for relevant biological insights that can be translated to human conditions.
What role do CD29, CD44, and Sca-1 play in stem cells?
These surface markers are associated with stem cell identity and are indicators of their health and functionality.
How long does the culture process take?
The initial culturing period is five days, with continuous observation required for later passage stages.
What are the potential applications of expanded BMSCs?
Expanded BMSCs can be used in therapies for tissue regeneration, drug testing, and studying stem cell biology.
