Localization of mRNA for SHIP2, SH2 domain-containing inositol polyphosphate 5-phosphatase, in the brain of developing and mature rats.

The localization of mRNA for SHIP2, SH2 domain containing inositol 5-phosphatase SHIP isozyme, was examined by in situ hybridization histochemistry in the brain of developing and mature rats. SHIP2 mRNA was first detected in the ventricular germinal zone at embryonic stages. As the postnatal development proceeded, the expression signal was evident in cell of the white matters, presumptive oligodendrocytes, and no significant expression was seen in neurons throughout the development.
