Real-Time Cell Cycle Imaging in a 3D Cell Culture Model of Melanoma, Quantitative Analysis, Optical Clearing, and...

Area of Science:

• Oncology
• Cell Biology
• Biotechnology

Background:

• Aberrant cell cycle progression is a key characteristic of solid tumors.
• Current cell cycle analysis methods often lack spatial information or provide only temporal snapshots.
• Understanding cell cycle dynamics is crucial for cancer research.

Purpose of the Study:

• To describe a novel technique for spatiotemporal real-time tracking of cell cycle progression in individual cells within a multicellular context.
• To provide a more detailed insight into solid cancer biology, including tumor growth, proliferation, invasion, and drug sensitivity.

Main Methods:

• Utilizing 3D melanoma spheroids generated from engineered melanoma cells.
• Employing the fluorescent ubiquitination-based cell cycle indicator (FUCCI) for real-time tracking.
• Integrating mathematical modeling with the FUCCI system for advanced analysis.

Main Results:

• The developed technique enables spatiotemporal, real-time monitoring of cell cycle progression.
• The system allows for detailed analysis of tumor growth, proliferation, and invasion dynamics.
• Insights into drug sensitivity within a multicellular tumor microenvironment can be obtained.

Conclusions:

• This technique offers a powerful tool for studying solid cancer cell biology in a more comprehensive manner.
• The combination of FUCCI and 3D spheroids provides a significant advancement over traditional cell cycle analysis methods.
• This approach facilitates deeper understanding of tumor behavior and response to therapies.
