Transient expression of SorCS in developing telencephalic and mesencephalic structures of the mouse

Here we describe the expression of a third member of the VPS10 domain containing receptor family, SorCS, during mouse embryonal and early postnatal nervous system development. SorCS is expressed in a unique transient and dynamic pattern in regions where cells proliferate, as well as in areas where already differentiated cells reside, including the cerebral cortex, the ventral tegmental area, and the globus pallidus. Transcripts were absent from fiber tracts hinting at a neuronal expression. The only exception was hybridization signals on the developing optic nerve correlating with the appearance of astrocytes migrating into the retina.
