CxV lifespan

Div	Axons	Cells leaving explant	Viability
1	Start growing	Migrate	Risk of detachment
2	300–600 µm	Migrate	Explant shrinks ± 0.5 µm
3	Up to 1.5 mm	Stay in 300 µm area near explants	Steady axon growth
7	Up to 2.2 mm		Axon growth slows down
14	Up to 2.75 mm	Migrated cells die	Risk of axon degeneration
