NCT01943175

Brief Summary

This study aims at finding endophenotypes of schizophrenia at neuronal level by obtaining stem cells which is derived from adipose cells of subjects with heavy genetic loading for schizophrenia then differentiating them into neuronal cells.

Outcome Measures

Primary Outcomes (1)

  • Structural and functional characteristics of neurons differentiated from adipose tissue derived stem cells in subjects with genetic high risk for schizophrenia and healthy controls

    in vitro measurement of the expression of the neuronal markers for differentiated post-mitotic neuron, GABAergic/Glutamatergic neuron. The neuronal connectivity, neurites from soma and synaptic protein levels will be assessed. In addition, RNA and proteins expression (e.g. Glutamate/GABA receptors) , physiological function, and in vitro response to antipsychotics will be evaluated.

    three years

Secondary Outcomes (7)

  • CAARMS(Comprehensive assessment of at risk mental states)

    Baseline

  • PANSS(Positive and Negative Syndrome Scale)

    Baseline

  • Neurocognitive function test battery (composite)

  • ERP(event-related potential) profile
