Gonaden-Mikroinjektion: Eine Methode zur direkten Verabreichung von Verbindungen in die Keimbahn von C. elegans

Executive Industry Relevance

Gonad microinjection in C. elegans enables direct germline delivery of compounds, supporting target validation and mechanistic de-risking in early discovery. This method provides a scalable, reproducible system for assessing gene function and phenotypic outcomes, informing lead identification and portfolio triage. By generating heritable genetic modifications, it enhances predictive confidence in preclinical models and reduces biological ambiguity in translational research.

Implementation Considerations

• Requires expertise in worm handling, microinjection techniques, and germline biology.
• Dependent on precision instrumentation including injection needles, micromanipulators, and compound-loaded capillaries.
• Necessitates standardized protocols for worm staging, immobilization, and post-injection recovery.
• Involves adaptation considerations for different compound types (e.g., RNP, DNA, RNA) and injection volumes.
• Limited by worm strain sensitivity and potential off-target effects requiring validation controls.
