Scientists Develop Glowing Cell Cycle Reporter in Chickens
A new transgenic chicken model lets researchers watch cell division in live embryos, a first for an avian species.
Updated on Nov. 6, 2026 in Life Sciences
Researchers have developed a fluorescent cell cycle reporter system in chickens, using fluorescent proteins that make cells glow in different colors across stages of division. The new model, named FuChi (Fucci Chicken), enables observation of cell division and growth in live cells and tissues of developing embryos.
Why it matters
Because the reporter works in live embryos, scientists can track how cells proliferate and migrate during early development rather than inferring it from fixed samples. The system is expected to support research into vertebrate development, disease and infection response.
The reporter is based on the Fucci (Fluorescent ubiquitination cell cycle indicator) technology, adapted by introducing reporters into chicken germ cells that were transplanted into surrogate host embryos. Quantitative performance data were not reported, and the outcome is described qualitatively as a first for avian species.
The players
Lancaster University
A public research university in England that collaborated on the development of the chicken cell cycle reporter system.
RIKEN Center for Brain Science
A major Japanese research institute that contributed as a collaborator on the study.
University of Edinburgh
A leading Scottish university that is home to the National Avian Research Facility and the Roslin Institute.
The details
The team introduced Fucci reporters into chicken germ cells and transplanted them into surrogate host embryos, then used the resulting males to generate embryos carrying the reporter. The team monitored proliferation across developing tissues, analyzed migrating cells, and performed live imaging during the earliest stages of embryonic development.

The Big Picture
The FuChi model extends the Fucci technology, originally built to visualize the cell cycle in cultured cells and model organisms, into an avian species for the first time. This brings live, in-embryo cell-cycle imaging to a vertebrate system that has long been important for developmental biology.
The reporter could eventually help researchers study how cells build tissues and respond to disease or infection in developing embryos. Practical applications are expected in future research rather than in immediate changes for the public.
The takeaway
Watching cells divide in living embryos gives scientists a direct view of development that fixed samples cannot provide. Researchers studying vertebrate biology now have a new avian tool for tracking growth and migration as it happens.
