بيض المخصب إيصال الجينات لينتيفيرال ساعد الليزر للماوس

Overview

This study addresses gene delivery in mouse fertilized eggs by laser perforation of the zona pellucida, allowing for transduction with lentiviral vectors. The protocol demonstrates a method for creating transgenic mice with minimal specialized skills required, which could have applications in other species.

Key Study Components

Research Area

• Genetics
• Developmental biology
• Gene delivery methods

Background

• Zona pellucida as a barrier in early embryonic development
• Challenges in gene delivery to embryonic cells
• Importance of developing transgenic models for research

Methods Used

• Laser-assisted perforation technique
• Mouse embryos as a biological model
• Lentiviral gene delivery system

Main Results

• 70% of healthy embryos develop into blastocysts; 47% of transduced embryos achieve the same
• 85% of transduced embryos express the gene of interest
• Technique supports rapid development of transgenic animal models

Conclusions

• The method effectively facilitates stable gene delivery in mouse embryos
• Significant implications for in vivo studies related to genetic diseases
