Developing Zebrafish Embryo Wins The 12th Annual Nikon Small World in Motion Competition

This year's Nikon Small World in Motion winning video showcases the developmental processes and evolutionary changes in a zebrafish

MELVILLE, N.Y., Sept. 13, 2022 /PRNewswire/ -- Nikon Instruments Inc. today unveiled the winners of the 12th annual Nikon Small World in Motion Video Competition. This year's first place prize was awarded to Dr. Eduardo E. Zattara for his visually striking video of lateral line cells and melanocytes migrating in a zebrafish embryo. Utilizing time-lapse imaging in an eight-hour window, Zattara's video highlights the beautiful and dynamic study of evolutionary developmental biology.

Melanin-forming cells known as melanocytes (colored in orange) move below the zebrafish’s skin to reach their final positions. While in green, sensory organ progenitors migrate along the lateral line of the zebrafish embryo. Zattara used fluorescence to contrast the various cell functions during this developmental period in the embryo.

"This recording came out very clean and required almost no post-processing. It is an astonishing display of the dynamics of cell migration during development," said Zattara. "The result was a video that was both biologically informative and visually striking. It was by far my favorite microscopy video to render."

Zattara went on to say, "While I maintain several lines of work ranging from genomics to community ecology, my main interest lies in the interaction between ecology, evolution and development. I am particularly interested in how developmental capabilities can affect evolutionary routes and ecological outcomes. While I like to consider all scales of life, I always focus on the organism to understand biological systems."

Eric Flem, Communications and CRM Manager, Nikon Instruments said, "This year's winning entry not only reflects the remarkable research and trends in science, but also gives the public a glimpse into a hidden world that can only be seen through a microscope. As imaging technologies continue to advance, we are seeing more scientifically relevant events in higher and more visually detailed quality."

Second place was awarded to Dr. Christophe Leterrier for his 12-hour time-lapse of cultured monkey cells labeled for plasma membrane (orange) and DNA (blue). In order to capture this video, Leterrier had to keep the cells alive throughout the entire acquisition time, with proper temperature and humidity control, as well as minimal phototoxicity from laser illumination.

Third place was awarded to Dr. Ahmet Karabulut for his video of sea anemone neurons and stinging cells showing their dynamic processes.

The 2022 judging panel included:

• Dr. Gustavo Menezes, Associate Professor and Head of the Center for Gastrointestinal Biology at the Federal University of Minas Gerais
• Dr. Nikolay Nikolov, Senior Video Journalist at The New York Times
• Annaliese Nurnberg, Photo Editor at The Washington Post
• Dr. Clare Waterman, Cell Biologist and Member of the National Academy of Sciences
