these findings suggest ( i ) that neurons are programmed , possibly at the time of neurulation , to generate high- or low-sialic-acid patterns of surface carbohydrates on their growth cones according to their origin , and ( ii ) that the specific glycoconjugate pattern found for each type of neuron may be involved in selective cell-cell interactions during nervous system development .
