What is electroporation?
Electroporation is a technique used to introduce DNA into cells by applying an electrical field.
Why use murine models for this study?
Murine models provide a controlled environment to study gene expression and retinal development.
What are the implications of manipulating gene expression in RGCs?
It can help understand the mechanisms of retinal diseases and potential therapeutic approaches.
How is GFP used in this research?
GFP serves as a marker to visualize successful gene transfer and expression in RGCs.
What are the potential risks of in utero electroporation?
Risks include potential harm to the embryos and the mother if not performed correctly.
Can these techniques be applied to other cell types?
Yes, similar electroporation techniques can be adapted for other cell types in various tissues.
