Background
- Understanding the role of mesenchymal cells in pancreas development is crucial.
- Mesenchymal cells provide extrinsic signals that influence epithelial development.
- Isolation of these cells can enhance our knowledge of pancreas function and related diseases.
- This method is applicable to various developmental stages of mice.
Purpose of Study
- To isolate pancreatic mesenchymal cells for gene and surface marker analysis.
- To investigate the cues expressed by mesenchymal cells.
- To understand how these cues influence epithelial development.
Methods Used
- Harvesting pancreatic tissues from mice and digesting them with a buffer.
- Filtering and sorting cells using flow cytometry.
- Staining cells for viability and surface markers.
- Extracting RNA for further analysis.
Main Results
- Distinct populations of YFP-labeled mesenchymal cells were identified across different ages.
