This year the students in Developmental Biology at Reed College have outdone themselves! We have 9 fantastic entries. Please let us know which one is your favorite by clicking here to vote for your favorite image. You’ll help the lucky recipient win a prize!
All of these images are the result of student research in the Dev Bio (BIOL 351L) class. If you have any questions about what each image actually is or about the specific research that led to these images, we’ll be happy to answer. Please post questions or comments below and we’ll respond.
Also, one entry didn’t quite make the deadline, but because it’s so spectacular, I’ve shared it below. When we found a spontaneous mutant embryo with two heads (born from wild-type parents), one of the students in my lab, Amanuel, wanted to know what the retinal ganglion cell projections looked like. He and another student, Aashis, fixed the embryo at ~4 days post fertilization and then stained the axons with an antibody toward acetylated tubulin. The movie below takes micometer-scale steps through the head of a four-eyed zebrafish, revealing the axons that leave the eyes and find their specific targets the brain(s). The eyes are located in the center and on either side of the image. Click on the image to open the movie and watch the optic nerves appear.
