Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Background:

Appendage regeneration in arthropods is obscured by their opaque exoskeletons.
Dynamic visualization of microstructural tissue regeneration is difficult.

Purpose of the Study:

To present a protocol for high-resolution imaging of arthropod appendage regeneration.
To enable dynamic visualization of microstructural tissue changes during regeneration.

Main Methods:

Tissue preparation and fixation.
Critical point drying for sample preservation.
Micro-computed tomography (micro-CT) scanning.
3D visualization of scanned tissues.

Main Results:

Successful capture of high-resolution details of microstructural tissues at specific regeneration points.
Demonstration of a feasible method for dynamic visualization.

Conclusions:

The micro-CT protocol offers a valuable tool for studying appendage regeneration in arthropods.
This technique enhances understanding of regenerative processes in insects and crustaceans.
