Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Analysis of the effects of three members of the FGF family (FGF1, FGF2 and FGF9) and bone morphogenic protein 4 (BMP4) on myelinating cultures generated from dissociated embryonic spinal cord. The results of both immediate (24 hours, T1 (24 hrs)) and long term treatments (10days, T2) give insights into the cumulative effects of sustained FGF and BMP mediated signal transduction in the pathogenesis of demyelinating diseases.

Description
Failure of remyelination in multiple sclerosis (MS) is associated with inhibition of oligodendrocyte precursor (OPC) differentiation, but the cellular and molecular mechanisms involved remain poorly understood. We now report inflammatory demyelination in MS is associated with localized expression of fibroblast growth factor 9 (FGF9) by oligodendrocytes and to a lesser extent astrocytes, and demonstrate FGF9 inhibits myelination and remyelination in vitro. This inhibitory activity is reversible and due to an off target FGF9-dependent effect on astrocytes that disrupts in the growth factor milieu required to support myelination.
