Grafting of embryonic motoneurons into spinal cord and striatum of adult mice. 1990

Department of Neurosurgery, University Hospital of Geneva, Switzerland.

The aim of the present work was to determine whether embryonic motoneurons could survive in the adult CNS and whether they display different survival and growth characteristics in their natural site (the spinal cord) as compared to an ectopic site (the striatal region of the brain). Specific labelling of embryonic motoneurons was obtained by retrograde transport of a fluorescent tracer (carbocyanine) followed by partial purification of the dissociated motoneurons on a density gradient. This technique offers the advantage that only the motoneurons in the cell suspension used for the grafts contain the fluorescent tracer. This study demonstrates that these motoneurons can survive and differentiate in the white and grey matters, not only in the adult spinal cord, but also in the brain. Furthermore, these motoneurons can migrate approximately 2 mm in the spinal cord and 4 mm in the brain.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D002465	Cell Movement	The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.	Cell Migration,Locomotion, Cell,Migration, Cell,Motility, Cell,Movement, Cell,Cell Locomotion,Cell Motility,Cell Movements,Movements, Cell
D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.
