Regeneration of the nervous system
Manuela Lahne

Research Interests:

My research investigates the mechanisms that lead to robust regeneration of retinal neurons following damage of the adult zebrafish retina. I specifically focus on a migratory behavior termed interkinetic nuclear migration that the proliferating cells in the retina, the Müller glia and the subsequently arising neuronal progenitor cells, undergo. During retinal development this migration exposes the nuclei of proliferating cells to different signaling gradients that are critical in determining whether the proliferating cells remain in the cell cycle or differentiate into the different neuronal subtypes of the retina. In the adult regenerating retina, interkinetic nuclear migration plays a similar role; however the signaling gradients have not been identified. Currently, I am investigating both the mechanisms that facilitate interkinetic nuclear migration and those that influence fate decisions of proliferating cells. My research uses a variety of techniques including live cell imaging and molecular biological methods. Understanding the mechanisms that orchestrate the regenerative response in the zebrafish retina will benefit our long-term aim to develop strategies that will overcome vision impairments in human.
