Fast Super-Resolution Live Cell Imaging of Nuclear Membrane-Endoplasmic Reticulum Dynamics.

Area of Science:

• Cell Biology
• Microscopy
• Molecular Biology

Background:

• The nuclear membrane is continuously remodeled during eukaryotic cell cycles.
• The endoplasmic reticulum is integral to the nuclear membrane and regulates its remodeling.
• Understanding these dynamics is crucial for cell cycle progression and function.

Purpose of the Study:

• To describe a detailed protocol for high-speed live-cell imaging of nuclear membrane/endoplasmic reticulum dynamics.
• To utilize super-resolution microscopy for capturing these dynamic events.
• To provide a method for visualizing nuclear membrane and endoplasmic reticulum structural changes across cell cycle stages.

Main Methods:

• Live-cell imaging using a fluorescent endoplasmic reticulum resident marker (GFP-KDEL).
• Application of super-resolution microscopy techniques.
• Protocol development for high-speed imaging of dynamic cellular structures.

Main Results:

• Successful high-speed imaging of nuclear membrane/endoplasmic reticulum dynamics in live cells.
• Visualization of structural changes at different cell cycle stages.
