Competition Winner:

Valerie Virta, PhD
Section on Vertebrate Development (Tom Sargent Lab)

Dividing cell: The lines are microtubules, visualized in the living embryos via GFP fused to tubulin. These are epithelial cells located over the yolk ball. One cell is shown dividing as the microtubules have arranged into the mitotic spindle.

Below is the image of Bone marrow derived Macrophage infected with Gram positive bacteria Listeria monocytogenes (in Red). In Macrophages infection with Listeria induces the phenomenon of Autophagy, an intracellular event that act as an innate cellular defense mechanism to kill invading bacteria. In this image we can see that most of the Intracellular bacteria are trapped in Autophagosomes (in Green), which is a unique structure formed during Autophagy.

(Photo credit: Samantha Haynie) Juvenile male monkeys engage in rough-and-tumble play, a behavior of interest at the LCE Field Station in Poolesville, MD. Researchers here study complex social interaction in monkeys with respect to kinship, dominance hierarchy, and physiology.

Alex Valm and Sarah Cohen's image

Alex Valm, PhD, and Sarah Cohen, PhD
Section on Organelle Biology (Jennifer Lippincott-Schwartz Lab)

A mouse embryonic fibroblast cell expressing fluorescent proteins that localize to peroxisomes (cyan), mitochondria (green), the endoplasmic reticulum (yellow), and lysosomes (red). The cell is also labeled with a dye that labels lipid droplets (magenta).

Alex and Sarah also submitted an accompanying movie (QuickTime format; to view, please download the QuickTime player or VLC Player).

Arches with neuron: The green is GFP expressed under the Sox10 promoter, which highlights neural crest cells. In this view, neural crest cells have differentiated into 2 cell types in particular. There are columnar cartilage cells forming the larval jaw, and a neural cell is highlighted in the brain. The faint red is an indicator of Bmp signaling via Kusabira Orange expressed under Bmp Response Elements (BRE).

GreenBMP_RedCNCC: This image shows three types of fluorescence using 2 colors in a live zebrafish embryo. A ventral view of the face depicts the mouth opening, the stomodeum, using detection of regular light so that anatomical features can be located with respect to the fluorescent components of the image. The semicircles on either side of the stomodeum are the eyes, and differentiating pigment cells autofluoresce in the red channel as spidery shapes. The green cells express an indicator of Bmp signaling via GFP expressed under Bmp Response Elements. The red cells around the stomodeum are visualized via membrane-associated RFP expressed under the Sox10 promoter, which highlights neural crest cells. Depending on the strength of the signal, some cells show both a red outline and a green fill, indicating they are neural crest cells experiencing Bmp signaling. Using these living fish, Bmp signaling can be observed during morphogenesis of craniofacial neural crest cells forming the zebrafish jaw elements.

MonetFace: This image shows green fluorescence of neural crest cells via GFP expressed under the Sox10 promoter, and red fluorescence of cells experiencing Bmp signaling via Kusabira Orange expressed under Bmp Response Elements. Cells that look yellow or orange are neural crest cells actively engaged in Bmp signaling. Using these living fish, Bmp signaling can be observed during morphogenesis of craniofacial neural crest cells forming the zebrafish jaw elements.
