Mouse embryonic fibroblasts forming focal adhesions
Congratulations to Alejandra Valdivia, PhD, winner of the Best Image contest held as part of the Emory Postdoctoral Research Symposium, which takes place next week (Thursday, May 19). She is in Alejandra San Martin’s lab, studying NADPH oxidase enzymes and how they regulate cell migration.
Valdivia submitted this image of mouse embryonic fibroblasts forming focal adhesions, points of contact of the cell with the extracellular matrix. Focal adhesions allow the cells to adhere and migrate.
Explanation: Red is for paxillin, a protein concentrated in focal adhesions. Green is phalloidin, a toxin from mushrooms that binds one type of the cytoskeletal protein actin, seen here as stress fibers. Blue is DNA, showing the cells’ nuclei.

Emory University School of Medicine’s Office of Postdoctoral Education has posted ten dazzling images from current Emory biomedical research here, and you can vote on your favorites (VOTE HERE). The Best Image contest sets the stage forÂ the Postdoctoral Research Symposium on May 19. A gallery showing all ten at once — larger than what you see below– is also available at this site.
Voting lasts only until Sunday (4/23), since the three contest-winning images will be part of the abstract book and other materials, and the organizers need to complete printing orders soon.
Lab Land is looking forward to learning more about the images. For now, it is fun to guess what they are. In the gallery, each one is labeled with the name of the researcher who submitted them. Read more
