Nikon Instruments Inc. today announced the winners of the 50th annual Nikon Small World Photomicrography Competition, celebrating five decades of excellence in microscopy and digital imaging. This year’s first place prize was awarded to Dr. Bruno Cisterna, with assistance from Dr. Eric Vitriol of Augusta University, for his groundbreaking image of differentiated mouse brain tumor cells, highlighting the actin cytoskeleton, microtubules, and nuclei. This image reveals how disruptions in the cell's cytoskeleton – the structural framework and “highways” known as microtubules – can lead to diseases like Alzheimer's and ALS.

Dr. Cisterna’s research revealed that profilin 1 (PFN1), a protein crucial for building the cell's structure, plays a key role in maintaining the microtubule highways essential for cellular transport. When PFN1 or related processes are disrupted, these highways can malfunction, leading to cellular damage similar to what is observed in neurodegenerative diseases.

"One of the main problems with neurodegenerative diseases is that we don't fully understand what causes them,” said Dr. Cisterna. “To develop effective treatments, we need to figure out the basics first. Our research is crucial for uncovering this knowledge and ultimately finding a cure. Differentiated cells could be used to study how mutations or toxic proteins that cause Alzheimer's or ALS alter neuronal morphology, as well as to screen potential drugs or gene therapies aimed at protecting neurons or restoring their function.”

His patience and determination were crucial in capturing his image. "I spent about three months perfecting the staining process to ensure clear visibility of the cells. After allowing five days for the cells to differentiate, I had to find the right field of view where the differentiated and non-differentiated cells interacted. This took about three hours of precise observation under the microscope to capture the right moment, involving many attempts and countless hours of work to get it just right.”

The hard work behind this discovery underscores its significance, bringing researchers closer to answers that could potentially transform millions of lives. “After three years of research, we finally published our findings four months ago in the Journal of Cell Biology, and there's still more work to be done,” said Dr. Cisterna. “I’m deeply passionate about scientific imaging; I’ve been following the Nikon Small World contest for about 15 years. It's an incredible contest that highlights the beauty of photomicrography but also inspires continued exploration and innovation in the field."

Eric Flem, Senior Manager, CRM and Communications at Nikon Instruments, shares a similar perspective on the competition. “At 50 years, Nikon Small World is more than just an imaging competition – it’s become a gallery that pays tribute to the extraordinary individuals who make it possible. They are the driving force behind this event, masterfully blending science and art to reveal the wonders of the microscopic world and what we can learn from it to the public.” He went on to add, “Sometimes, we overlook the tiny details of the world around us. Nikon Small World serves as a reminder to pause, appreciate the power and beauty of the little things, and to cultivate a deeper curiosity to explore and question.”

Second place was awarded to Dr. Marcel Clemens for his image of an electrical arc between a pin and a wire, produced by applying a potential difference of 10,000 volts.

Third place was awarded to Chris Romaine for his image of a cannabis plant leaf. The bulbous structures are trichomes, or hair-like plant appendages, and the bubbles inside are cannabinoid vesicles, fluid-filled, blister-like structures.

In total, Nikon Small World recognized 87 photos out of thousands of entries from scientists and artists across the globe.

The 2024 judging panel included:

• Adrian Coakley, Director of Photography at National Geographic Books
• Michelle S. Itano, Ph.D., Assistant Professor of Cell Biology and Physiology and Director of the Neuroscience Microscopy Core at the University of North Carolina at Chapel Hill
• Emily Petersen, Photography Managing Editor at Science Magazine
• Clare Waterman, Ph.D., Cell Biologist and Member of the National Academy of Sciences
• Jennifer C. Waters, Ph.D., Director of the Core for Imaging Technology & Education at Harvard Medical School
• Samantha Yammine, Ph.D., Neuroscientist and Science Communicator
