Primary News: Research Brief: From Fibroblast to Neuron in One Easy Step

This is a remarkable achievement. If we can translate this research to clinical settings, we may be able to gently nudge fibroblast cultures collected from people with schizophrenia into expressing neuronal phenotypes (and then compare with similar tissue from healthy controls). To date, studies based on fibroblast cultures from patients with schizophrenia have found mixed results. While one has been disappointing with respect to gene expression (Matigian et al., 2008), others have found convergent evidence for altered cell cycle properties (Wang et al., 2010; Catts et al., 2006).

If the new technology can be used in adult human fibroblast tissue, the resultant neural cultures may provide us with glimpses into dysfunctional pathways associated with schizophrenia.
