Movie 2

Lineage tree of tracked WT spinal cord progenitors exposed to EGF.
NPCs obtained from E15 spinal cords were cultivated in the presence of either EGF or FGF2 and followed over a period of 96 hours. In the movies you can follow simultaneously the creation of the lineage tree (left side) of a specific cell (right side) and all of their siblings marked with red numbers obtained by time-lapse video microscopy. Tracking was performed with the programme tTt.
