Abstract

Interneurons in the olfactory bulb (OB) are generated from neuronal precursor cells migrating from anterior subventricular zone (SVZa) not only in the developing embryo but also throughout the postnatal life of mammals. In the present study, we established an in vivo electroporation assay to label SVZa cells of rat both at embryonic and postnatal ages, and traced SVZa progenitors and followed their migration pathway and differentiation. We found that labeled cells displayed high motility. Interestingly, the postnatal cells migrated faster than the embryonic cells after applying this assay at different ages of brain development. Furthermore, based on brain slice culture and time-lapse imaging, we analyzed the detail migratory properties of these labeled precursor neurons. Finally, tissue transplantation experiments revealed that cells already migrated in subependymal zone of OB were transplanted back into rostral migratory stream (RMS), and these cells could still migrate out tangentially along RMS to OB. Taken together, these findings provide an in vivo labeling assay to follow and trace migrating cells in the RMS, their maturation and integration into OB neuron network, and unrecognized phenomena that postnatal SVZa progenitor cells with higher motility than embryonic cells, and their migration was affected by extrinsic environments.
