Many lines of evidence indicate that genetically distinct subtypes of motor neurons are specified during development, with each type having characteristic properties of axon guidance and cell-body migration. Motor neuron subtypes express unique combinations of LIM-type homeodomain factors that may act as intrinsic genetic regulators of the cytoskeletal events that mediate cell migration, axon navigation or both. Although experimentally displaced motor neurons can pioneer new routes to their… CONTINUE READING
