Functional maturation of the oligodendrocytes and myelin basic protein expression in the olfactory bulb of the mouse.

Abstract

The timing of myelin basic protein (MBP) expression and myelin component synthesis by the oligodendrocytes of the olfactory bulb was investigated in the mouse. Immunostaining with an anti-MBP immunoserum and a radioimmunoassay determination of MBP allowed to study the timing of MBP deposition during the development in this structure. Immunostaining of dissociated cells with anti-MBP and anti-galactosylceramide (anti-GC) was used to determine the state of development when these markers become expressed by olfactory bulb oligodendrocytes. Investigations using dissociated cells showed that GC-positive oligodendrocytes are already detected 3 days after birth in the olfactory bulb of the mouse and MBP is expressed 4 days later. Myelinated fibers were not visible on cryostat sections of olfactory bulb before 8 days postnatal. This work has been initiated by observations on the timing of myelination of olfactory bulb oligodendrocytes in transplantation experiments.
