Summary
Researchers developed a new fixation protocol to preserve delicate cell structures called cytonemes. This method enables detailed study of protein localization and morphogen transport within these crucial cellular extensions.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Immunocytochemistry is vital for analyzing protein composition and localization in cells.
- Traditional methods fail to preserve cytonemes, specialized filopodia essential for morphogen transport.
- This limitation hinders the mechanistic study of cytoneme regulation.
Purpose of the Study:
- To develop a novel fixation protocol for cultured cells that preserves cytonemes.
- To enable immunofluorescent analysis of proteins within these delicate cellular structures.
Main Methods:
- Development of a specialized cell fixation protocol.
- Application of immunofluorescence techniques to analyze preserved cytonemes.
Main Results:
- The new protocol effectively preserves the structural integrity of cytonemes in cultured cells.
- Allows for detailed visualization and analysis of protein localization within cytonemes.
Conclusions:
- The developed fixation protocol overcomes limitations of traditional methods.
- Facilitates in-depth investigation into the mechanisms regulating cytonemes and morphogen transport.

01:25Overview of Electron Microscopy
13.8K
The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.

5.4K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

5.4K
Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.

Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

01:20Preparation of Samples for Electron Microscopy
6.9K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...
