this is often done through cell-cell interactions
for instance, in neurogenesis
stem cell divide at the neural tube
then migrate to location via radial glia
along the path they divide again to become more specialized
e.g. what type of neural cell
once on location neurotrophins (proteins) initiate axon growth
this spurs synaptogenesis
then synaptic pruning through Hebbian processes
