LMB 365 – Day 215

Day 215 of #LMB365 is an image of an embryonic day 12 mouse lung, showing the beginning of the extensive branching morphogenesis that will eventually form the adult mouse lung. The tubes of the forming lung are shown in green, and the surrounding supporting tissue is in magenta. The work was carried out by Katja Roeper in collaboration with Emma Rawlins at the Gurdon Institute.
