Collecting duct of three different embryonic mouse kidneys growing in ex vivo culture systems and captured every 20 minutes for 2 days. The kidneys express a nuclear-localized Green Fluorescent Protein which has been pseudocolored in three different colors and overlaid. The purpose of the overlay is to highlight the highly conserved branching behavior of these three different kidneys. The kidneys were cultured separated and digitally combined.
