The cellular mechanisms involved in axonogenesis are still unclear. In the present work we found that formation of neurites in cultured neonatal dorsal root ganglion neurons co-incided with the redistribution of highly charged mitochondria. Radially distributed in subplasmalemmal space 3 h after plating, highly charged mitochondria formed clusters in the hillocks of predominant neurites during the next 2448 h and then redistributed into the axons. These results provide evidence that accumulation of a critical mass of charged mitochondria at the site of the future axonal hillock may represent the slow initiation stage of axonogenesis, followed by a fast growth phase. |
