The Page Lab studies the origins of sexual dimorphism. During fetal development, cells of the embryonic testis are organized to form tubes. The organizer nurse cells (blue) arrange cells that will ultimately become sperm (red) to create the germ cell niche.
The Sive Lab studies vertebrate development, using frogs and zebra fish (pictured) because they are amenable to genetic, molecular, and live imaging approaches. The red in the photo is actin, the blue nuclei, the green ER.
Professor Bob Horvitz is a recipient of the Nobel Prize. Pictured is a reconstruction from serial-section electron micrographs of the front half of the pharynx of C. elegans, showing different cells (labeled) in different colors.
The Reddien Lab uses planarians as a model organism for studying regeneration. Following RNA interference of the gene beta-catenin-1 and infliction of multiple injuries, this planarian regenerated six heads.
