Frequently Asked Questions

What is the main advantage of this microscopy technique?

It preserves the native physiological environment of cells while allowing for live imaging.

How important is the dissection technique?

It is crucial to avoid damaging the testes during isolation and mounting.

What type of imaging is used in this protocol?

Fluorescence microscopy is used for live imaging of cell division.

What organisms are used in this study?

Drosophila larvae and early pupae are used for isolating testes.

Is visual demonstration important for this protocol?

Yes, it helps researchers learn how to properly isolate and mount the testes.

What is the purpose of this study?

To analyze cell division mechanisms in intact tissue using microscopy.

The goal of this protocol is to analyze cell division in intact tissue by live and fixed cell microscopy using Drosophila meiotic spermatocytes. The protocol demonstrates how to isolate whole, intact testes from Drosophila larvae and early pupae, and how to process and mount them for microscopy.

This protocol can be used to analyze the mechanisms of cell division in the context of living, intact tissue using fluorescence microscopy. The main advantage of this technique is that cells'native physiological environments are preserved, while also allowing for live imaging over long time courses. The most important part of this technique is making sure that the testes are not damaged during dissection or mounting.

This is a skill that is acquired with a little bit of time and practice. Visual demonstration of this method is critical, because it shows how to identify and isolate the testes, and how to mount them for imaging without damaging the tissue. Prepare animals, tools, and media as described in the manuscript.
