Hypothesis
Can we standardize the procedure for subretinal injection and optimize electroporation conditions for gene delivery in mouse eyes?
Conclusion
A standardized surgical method and a clear indicator of successful surgery were crucial for establishing an effective gene delivery system using electroporation.
Supporting Evidence
- An 80% success rate was achieved using the standardized method.
- Electroporation conditions were optimized to achieve approximately 30% efficiency in RPE transfection.
- Three blebs in the eye indicated a successful subretinal injection.
Takeaway
The researchers found a better way to inject genes into mouse eyes and make sure the surgery works by creating visible blebs in the eye.
Methodology
Mice underwent subretinal injections followed by electroporation to deliver plasmid DNA, with conditions optimized for efficiency.
Limitations
The technique requires significant practice to master, and the variability in outcomes can still affect results.
Participant Demographics
C57BL/6, 129/Sv, and Balb/C mice aged 1 to 4 months were used.
