Overview
This article describes methods for isolating primary mouse epicardial cells using an outgrowth culture assay and assessing the functional migration of epicardial-derived cells (EPDC) through an ex vivo heart culture system. These protocols are designed to identify genetic and chemical modulators of epicardial epithelial-to-mesenchymal transition (EMT) and motility.

What are epicardial-derived cells?
Epicardial-derived cells are progenitor cells that originate from the epicardium and play a role in cardiac development and repair.
Why is the outgrowth culture method important?
It allows for the isolation of primary epicardial cells, which are essential for studying their behavior and potential in regenerative medicine.
How does the ex vivo heart culture system work?
The ex vivo heart culture system provides a controlled environment to assess the migration and behavior of epicardial-derived cells in a heart-like setting.
What is epithelial-to-mesenchymal transition (EMT)?
EMT is a biological process where epithelial cells lose their characteristics and gain migratory and invasive properties, which is crucial in development and tissue repair.
What are the implications of this research?
The research has implications for developing strategies to manipulate epicardial cell biology, which could enhance cardiac regenerative therapies.
What is the significance of using mouse embryos for cell isolation?
Mouse embryos provide a reliable source of epicardial cells for research, allowing for controlled studies on cell behavior and development.
