Research Abstract

To understand the molecular mechanisms underlying neuronal dysfunctionand celldeath caused by loss of ALS2, we tried togenerateALS2 deficient cellular model using marmoset ES cells. We succeededin determining ALS2 sequence in marmoset, and cloned siRNA-mediated ALS2down-regulatedmarmoset ES cells. By differentiating theseES clones, we will analyzethe function of ALS2 in primate motor neuron.
