[Neuroblast differentiation and migration in the developing human spinal cord in the 1st half of prenatal ontogenesis].

The processes of neuroblasts differentiation and migration in the developing human spinal cord in the first half of antenatal ontogenesis were studied by the Golgi method. The neuron development was traced from the neuroepithelial matrix cells to the maturing neurons. A possible role of a special neuroblast outgrowth as a channel for its nucleus migration to the definite typological position of the mature neuron is suggested.
