    Journal: Brain Res; 1987 Sep 08; 420(1):39-47. PubMed ID: 3676754.
    Abstract:
    The shiverer model allows for the immunocytochemical staining of the patches of myelin formed by transplanted oligodendrocytes from a normal newborn mouse. Fragments of the olfactory bulb were transplanted into various parts of the brain to place the myelinating cells in different anatomical conditions. Whole brains were horizontally sectioned in order to study the full pattern of migration and myelination of the grafted oligodendrocytes. Transplanted oligodendrocytes were capable of short and long distance migration before their differentiation. Long distance migration occurred in the caudal as well as in the rostral direction and into the contralateral part of the brain through the commissures. The patches of immunoreactive myelin were mainly found in the large myelinated bundles: corpus callosum, internal capsule, fimbria-fornix, medial lemniscus, cerebellar peduncles and spinal cord funiculi. Some sites of migration indicate that oligodendrocytes followed at least two different axonal pathways successively. The thalamic area which contained numerous patches could be a place where oligodendrocytes switch from one fasciculus to another.
