Gene transfer is a powerful tool for functional gene analysis in human cells. In this respect, there is a need to develop experimental models that involve homogeneous cultures of human neuron‐like cells susceptible to gene transduction and that are easy to handle. Here we describe an optimized and reproducible procedure to differentiate human SH‐SY5Y neuroblastoma cells into a homogeneous population of neuron‐like cells. The fully differentiated cells are postmitotic and resemble primary cultured neurons in terms of their cytoskeletal polarity. Notably, differentiated SH‐SY5Y cells are far more susceptible to transduction by herpes simplex virus (HSV‐1)‐based vectors than proliferating SH‐SY5Y cells. This increase in transduction efficiency after neuronal differentiation may be due to the up‐regulation of cell surface receptors for herpesvirus entry. In summary, we propose that fully differentiated human neuron‐like cells obtained from the SH‐SY5Y neuroblastoma may constitute an excellent and versatile experimental tool for gene transfer and functional genomic studies with HSV‐1 vectors. © 2006 Wiley‐Liss, Inc.
