简介：
Overview
This protocol demonstrates the use of in utero electroporation to analyze neural development and migration in transgenic mouse models. It helps determine whether observed phenotypes result from intrinsic cellular mechanisms or environmental interactions.
Key Study Components
Area of Science
- Neuroscience
- Developmental Biology
- Transgenic Mouse Models
Background
- Neuron migration is influenced by both cell autonomous and non-cell autonomous factors.
- In utero electroporation allows targeted gene manipulation in specific brain regions.
- This technique simplifies phenotype analysis by excising genes from a small population of neurons.
- Visual demonstrations are crucial due to the delicate nature of embryos.
Purpose of Study
- To analyze defects in neural development and migration.
- To assess the role of specific genes in neuronal behavior.
- To improve understanding of cell-environment interactions during development.
Methods Used
