Time-Lapse Into Immunofluorescence Imaging Using a Gridded Dish

Area of Science:

• Cell Biology
• Mechanobiology
• Microscopy Techniques

Background:

• Live-cell imaging provides dynamic cellular information, while immunofluorescence offers static molecular details.
• Connecting these imaging modalities is crucial for understanding cellular processes like nuclear bleb formation but is often technically challenging.
• Existing methods require specialized software or stage position tracking, hindering accessibility.

Purpose of the Study:

• To develop a simplified protocol for directly correlating time-lapse live-cell imaging with subsequent immunofluorescence imaging.
• To provide an accessible method for cell biologists to link cellular dynamics with molecular composition.
• To overcome the limitations of current techniques in connecting live and static imaging.

Main Methods:

• Cells were cultured and imaged using time-lapse microscopy on gridded imaging dishes.
• The gridded coordinate system on the dish allowed for precise relocation of individual cells after live-cell imaging.
• Standard immunofluorescence staining was performed on the same cells, guided by the established coordinates.

Main Results:

• The protocol successfully enabled direct matching of cells between time-lapse and immunofluorescence images based on coordinates.
• This method eliminated the need for third-party analysis software or complex stage position measurements.
• The time-lapse into immunofluorescence (TL into IF) protocol proved straightforward and effective for mechanobiology research.

Conclusions:

• Time-lapse into immunofluorescence (TL into IF) imaging provides a direct and accessible link between live-cell dynamics and static immunofluorescence.
• The use of gridded imaging dishes is the key innovation, simplifying cell tracking and correlation.
• This protocol enhances the ability of cell biologists to study dynamic cellular events and their molecular consequences.
