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...
X-ray Imaging01:24

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
Bone Structure01:55

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Area of Science:

  • Biomaterials Science
  • Orthopedic Research
  • Nanotechnology

Background:

  • Bone strength is linked to nanoscale ultrastructural properties.
  • Previous studies lacked 3D analysis of these properties.
  • Lacuno-canalicular network, collagen, and mineralization are key factors.

Purpose of the Study:

  • To investigate human bone ultrastructure in 3D.
  • To analyze the 3D organization of the lacuno-canalicular network.
  • To characterize nanoscale mineralization and collagen fiber arrangement.

Main Methods:

  • Utilized X-ray phase nanotomography for high-resolution 3D imaging.
  • Examined osteonal and interstitial human bone tissue.
  • Analyzed nanoscale density variations and structural organization.

Main Results:

  • Detailed 3D morphology of the lacuno-canalicular network was elucidated.
  • Nanoscale density variations revealed hypermineralization at the cement line.
  • Collagen fibers exhibit a 3D twisted plywood structure.

Conclusions:

  • X-ray phase nanotomography enables unprecedented 3D bone ultrastructure analysis.
  • The 3D twisted plywood collagen structure is a novel finding.
  • Understanding these nanoscale features is crucial for bone mechanics and health.
