The annual Nikon Small World competition encourages scientists, photographers and hobbyists from around the world to showcase proficiency and photographic excellence of photography taken under the microscope. In this article you can find a selection of the top entries including the winning zebrafish face.
Dr. Ruiz brings the world face-to-face with his research on facial development and cellular morphogenesis with his winning image of a four-day-old zebrafish embryo. Dr. Ruiz uses the zebrafish to study genetic mutations that lead to facial abnormalities such as cleft lip and palate in humans in the lab of Dr. George Eisenhoffer at The University of Texas MD Anderson Cancer Center in Houston, Texas.
The judges were intrigued by Ruiz’s innovative techniques to capture time-lapse images of the developing zebrafish face. Using the time-lapse as a guide, Ruiz is creating an atlas of the development of the zebrafish face. His group is tracking physical landmarks throughout development to create a series of metrics that can be used to accurately describe the cellular movements that occur during the normal development of the face. These metrics can then be used to identify abnormalities in the development of zebrafish harbouring specific genetic mutations identified in human patients. He hopes that these findings will help provide insight into the cellular and molecular mechanisms that are altered in patients with facial deformities.
“Until now, these facial abnormalities had not been extensively studied in a live context where you can see what’s happening during development in real-time,” said Ruiz. “Using a live-imaging approach means we can better understand and pinpoint exactly how and why these developmental abnormalities occur. The first step is knowing how it happens, then we can figure out how to fix it.”
