Multicolor Cell Lineage Tracing Using MAGIC Markers Strategies.

Area of Science:

• Neuroscience
• Developmental Biology
• Genetics

Background:

• Multicolor MAGIC Markers are valuable for studying brain development at a multicellular level.
• Lineage tracing is crucial for understanding cell fate and tissue development.

Purpose of the Study:

• To describe a detailed in utero electroporation protocol for simultaneous labeling of multiple neural progenitors and their progeny.
• To showcase the utility of multicolor reporters for cell and lineage tracking in brain development.

Main Methods:

• In utero electroporation technique for introducing genes into embryonic neural progenitors.
• Utilizing multicolor MAGIC Markers for simultaneous labeling.
• Surgical protocol encompassing preoperative preparation and postoperative care.
• Non-integrative and integrative approaches for cell tracking.

Main Results:

• Successful simultaneous labeling of multiple neighboring progenitors and their respective progeny.
• Demonstration of diverse cell and lineage tracking possibilities over time.
• Established a comprehensive understanding of the surgical protocol for successful electroporation.

Conclusions:

• The described in utero electroporation method with multicolor MAGIC Markers is an effective strategy for multicellular lineage tracing in brain development.
• This approach provides a robust tool for investigating progenitor cell behavior and developmental trajectories.
