Andras Simon's Group
Natural examples of regeneration, such as salamanders, may unravel novel strategies for cell replacement of damaged or lost tissues. We study regeneration mechanisms in an aquatic salamander, the newt, which has the widest repertoire of regenerative abilities among adult vertebrates.
Our group has two main interests. The first dimension of our research is to reveal how adult neurogenesis and brain regeneration takes place. Here we focus on dopamine neurons in the midbrain. In particular we focus on the role of neurotransmitter signaling in neurogenesis during normal physiological conditions and also after neuronal ablation.
The second dimension of our research is to understand how skeletal muscle contributes to new tissues during limb regeneration. We have identified a Pax7+ stem cell population in salamander skeletal muscle and we try to understand how these cells take part in limb regeneration. Salamander skeletal muscle may also undergo a unique dedifferentiation process during limb regeneration, and we aim to reveal the mechanisms underlying skeletal muscle dedifferentiation.
