Stem Cell Scaffolds: Neural stem cells extend fibers that act as “rail road tracks” for migrating neurons (blue) and glial cells (green).

Xiaoti Xu, Leica DM 5000 upright fluorescence microscope
Mending Muscle: A mouse leg muscle heals itself after injury by generating new fibers from transplanted human muscle stem cells (blue nuclei).

Connor Ludwig, Leica epifluoresence microscope
Protein Palette: Different forms of tau protein, one in red and magenta and the other in teal and green, co-localize in a mouse brain.

Sarah Headland, Leica SP5
Homing Hemocytes: Immune cells in a fruit fly cluster in patches; white regions on this intensity map have the most cells, followed by blue and red.

Anna Reade, custom-made Light sheet fluorescent microscope (LSFM)
Tipping Point: A growing plant root tip (Arabidopsis sp.) bends as it grows. Cell nuclei are in blue and cell membranes in green.

Katrina Gold, Leica SF5
Blood Barrier: In a fruit fly’s thorax, blood cells (red) cluster around dark-blue air sacs, acting as immune sentinels against infection.

Donald McCarthy, Zeiss scanning electron microscope
Lapsing Lung: A fibrotic mouse lung where deposited matrix (left) and infiltrating cells (right) impair gas exchange in the alveoli.

Harrison Liu, Zeiss Axlovert
Bi-lobed Brain: A fly embryo’s two-lobed brain extends into its spinal cord, from where motor neurons branch out to form connections with muscles.

Xiaoyu Shi, 3D STORM microscope
Cilia Up-Close: Individual microtubules (pictured in green) form the cylindrical shapes of cilia on mouse tracheal cells.

Lauren Rodda, Leica SP5 Confocal Microscope
Bowel Balance: Ringed patches of immune cells in the small intestine keep gut microbes in check.

Gilad Doitsh, Electron microscope
T-cell Takeover: HIV virus particles multiply within an infected human helper T-cell.

RUNNER-UP
Daniel Kopink, Leica SPE
Fat Filler: Adipose cells (red) infiltrate a mouse skeletal muscle (green) degenerating after a chronic injury.

RUNNER-UP
Anna Reade, Digitally scanned light sheet microscope
Mouthing Off: A single-celled organism (Stentor sp.) forms a second mouth, ringed by cilia to sweep food in, as it prepares to divide.

GRAND PRIZE WINNER
Torsten Wittmann, Widefield epifluorescence microscope
Power Packed: In endothelial cells, the actin cytoskeleton (white) surrounds energy-making organelles known as mitochondria (gold). Cell nuclei are seen in blue.

Victoria Butler, Zeiss Axiolmager M2 microscope
Woozy Worms: Two larval nematodes (Caenorhabditis elegans) wrapped around each other while being anesthetized.

Huy Nguyen
Drop Dispenser: The life-blood tubes of a microfluidic dispenser connect to a central computer via 24 valves.
