We are delighted to announce the 2016 winners of our annual “Art in Science” competition. We were pleased to receive a multitude of scientifically intriguing and aesthetically striking images from the Penn research community. We have awarded four prizes: one for Postdoctoral Fellows and three for Graduate Students. It is our pleasure to share the winning images below.
Oocyte polarity is key to embryonic development and is established by the Balbiani body (Bb), a universal oocyte structure composed mainly of mRNP granules and mitochondria. We traced the symmetry-breaking events that initiate Bb formation in the zebrafish oocyte to the onset of meiosis.

We are studying mutant mice that lack the gene Zswim6. We recently discovered that they are deaf, so to understand why, we have been looking at different parts of the auditory system. This image shows that the inner ear is formed normally and does not account for the animals' deafness.
This image shows a dorsal root ganglia co-cultured with motor neurons. We are testing if the regenerating axons of motor neurons preferentially grow along established motor or sensory axons. We intend to use this knowledge to optimize our tissue engineered nerve grafts for treatment of peripheral nerve injury.
The embryonic head was recently identified as a source of hematopoietic stem cells (HSC). Before mapping the location of hematopoietic and hemogenic endothelial cells in the head, I first needed to determine the location of the arteries, veins and capillary beds.
