Expanding the Caenorhabditis elegans toolkit with gonad explants

Area of Science:

• Developmental Biology
• Cell Biology
• Genetics

Background:

• Animal development involves complex, coordinated pathways.
• Tissue explants offer simplified models for studying dynamic biological events.
• Investigating C. elegans germline development requires robust experimental systems.

Purpose of the Study:

• To establish and validate extruded C. elegans gonads as a functional tissue explant system.
• To demonstrate the utility of this system for live-cell imaging and drug-based mechanistic studies.
• To decipher mechanisms governing C. elegans germline development.

Main Methods:

• Extrusion of C. elegans gonads to create tissue explants.
• Live-cell imaging to observe cellular processes within explants.
• Treatment of explants with nocodazole, a microtubule-depolymerizing drug.

Main Results:

• C. elegans gonad explants maintain key in vivo developmental processes like mitosis, meiosis, apoptosis, and gametogenesis.
• Explants exhibit acute sensitivity to nocodazole treatment, indicating preserved cellular responses.
• The system successfully supports combined live-cell imaging and drug perturbation.

Conclusions:

• Extruded C. elegans gonads represent a tractable and valuable model for studying germline development.
• This explant system facilitates mechanistic investigations into dynamic cellular events.
• The combination of live imaging and drug treatment in this model advances understanding of developmental processes.
