'Celldance' spotlights cell biologists' images and videos
Date:12/11/2010

e in large part motivated by the beauty they see in cells every day of their professional life," said Chisholm. "In one sense, working with cells is like working in an art gallery where the art changes every day."

The 2010 "Celldance" winning images and videos will be posted online at www.ascb.org following the ASCB annual meeting.

Prior to public posting, journalists, editors, and news producers can obtain high-resolution still images and video clips of the 2010 "Celldance" winners by contacting: Cathy Yarbrough: sciencematter@yahoo.com, 858-243-1814; or John Fleischman: jfleischman@ascb.org, 513-706-0212.

Winning "Celldance" 2010 awards:

1st PLACE: VIDEO:

U. Serdar Tulu, Ph.D., of Duke University, for his film, "Cellular Recognition," showing the dynamics of the slender cytoplasmic projections, filopodia, during the development of a fruit fly (Drosphila melanogaster) embryo. In a process known as dorsal closure, two epidermal cell sheets are shown coming together to form a seamless epidermis.

1st PLACE: IMAGE:

Li He, graduate student at Johns Hopkins University, for "Actomyosin and Focal Adhesion in Fly Egg Chamber," a confocal micrograph of the follicle cells of a fruit fly egg chamber stained in three colors to mark actin filaments: DAPI (blue) to detect nuclei, GFP-paxillin (green) to identify focal adhesions, and rhodamine phalloidin (red) to mark actin filaments. Paxillin was driven by a heat shock promoter, which gave rise to the mosaic mosaic pattern. Myosin II was driven by its endogenous promoter. At cellular level, the myosin fibers are enriched at the basal side of follicle epithelia cells. The focal adhesion sites labeled by paxillin anchor both ends of the myosin stress fibers onto the basal membrane and relay the force generated by myosin contraction to the extra-cellular mat
