Figure 1. Dopaminergic neurons differentiated from induced pluripotent stem cells in vitro. Some processes that may contribute to neuron death can be assessed and modulated in vitro although those that are linked to aging are more difficult to replicate. Shown are neurons immunostained for BIII-tubulin (green) and alpha-synuclein (red).
