简介：
Overview
This article describes a protocol for the separation of mouse embryonic facial ectoderm and mesenchyme. The procedure involves treating whole embryos with Dispase II, isolating facial prominences, and carefully separating the ectoderm from the mesenchyme.
Key Study Components
Area of Science
- Neuroscience
- Developmental Biology
- Embryology
Background
- Understanding facial development in embryos is crucial for studying congenital disorders.
- Separation of ectoderm and mesenchyme is essential for various experimental applications.
