To determine the impact of copy number variation at the 1q21.1 locus on neuronal development, researchers generated iPSCs from individuals harbouring 1q21.1 deletion or duplication and differentiated them into functional cortical neurons.

Scientists examined epigenome remodeling at the onset of human nuclear reprogramming by profiling human fibroblasts after fusion with murine ESCs. Efficient reprogramming of human fibroblasts to iPSCs was achieved by transduction with vectors expressing SOX2, KLF4, and inducible dnAP-1, demonstrating that dnAP-1 can substitute for exogenous human OCT4.
