This study presents a protocol for ex vivo calcium imaging in Drosophila, enabling researchers to study live signal propagation in complex tissues. This method allows for extended organ culturing and calcium dynamics observation for various biological processes and drug discovery.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Cell Biology

Background:

  • Calcium signaling is crucial for conserved biological processes like cell differentiation, proliferation, and communication.
  • Studying live calcium dynamics in complex tissues is essential for understanding these fundamental processes.

Purpose of the Study:

  • To establish a protocol for ex vivo calcium imaging in Drosophila organs.
  • To enable the study of live signal propagation and calcium dynamics in complex tissues.
  • To facilitate pharmacological testing for target identification and therapeutic development.

Main Methods:

  • Isolation of Drosophila organs, including the developing wing imaginal disc and larval brain.
  • Extended culturing of isolated organs (up to 10 hours).
