FUCCI Reporter Gene-Based Cell Cycle Analysis.

Area of Science:

• Cell Biology
• Molecular Biology

Background:

• Cell proliferation is a key parameter in cellular analysis.
• The fluorescence ubiquitin cell cycle indicator (FUCCI) system allows live observation of cell cycle progression.
• FUCCI relies on fluorescently labeled proteins cdt1 and geminin to distinguish cell cycle phases.

Purpose of the Study:

• To generate NIH/3T3 cells stably expressing the FUCCI reporter system.
• To demonstrate the utility of FUCCI-expressing cells in 3D culture assays.
• To provide a protocol adaptable for other cell lines.

Main Methods:

• Lentiviral transduction was used to introduce the FUCCI reporter system into NIH/3T3 cells.
• Fluorescence imaging was employed to monitor cell cycle phases based on protein activity.
• 3D culture assays were performed using the engineered cells.

Main Results:

• Successfully generated NIH/3T3 cells stably expressing the FUCCI reporter.
• Demonstrated the ability to track cell cycle progression in real-time within 3D cultures.
• Validated the FUCCI system for assessing proliferative activity in a 3D environment.

Conclusions:

• The FUCCI reporter system is effective for monitoring cell cycle progression in NIH/3T3 cells.
• This method facilitates live and in vivo observation of cell proliferation in 3D cultures.
• The described protocol is adaptable for use with other cell lines, broadening its applicability.
