Abstract: A rapid and simple procedure is presented to obtain nearly pure populations of human neuron‐like cells from the SH‐SY5Y neuroblastoma cell line. Sequential exposure of SH‐SY5Y cells to retinoic acid and brain‐derived neurotrophic factor in serum‐free medium yields homogeneous populations of cells with neuronal morphology, avoiding the presence of other neural crest derivatives that would normally arise from those cells. Cells are withdrawn from the cell cycle, as shown by 5‐bromo‐2′‐deoxyuridine uptake and retinoblastoma hypophosphorylation. Cell survival is dependent on the continuous presence of brain‐derived neurotrophic factor, and removal of this neurotrophin causes apoptotic cell death accompanied by an attempt to reenter the cell cycle. Differentiated cells express neuronal markers, including neurofilaments, neuron‐specific enolase, and growth‐associated protein‐43 as well as neuronal polarity markers such as tau and microtubule‐associated protein 2. Moreover, differentiated cultures do not contain glial cells, as could be evidenced after the negative staining for glial fibrillary acidic protein. In conclusion, the protocol presented herein yields homogeneous populations of human neuronal differentiated cells that present many of the characteristics of primary cultures of neurons. This model may be useful to perform large‐scale biochemical and molecular studies due to its susceptibility to genetic manipulation and the availability of an unlimited amount of cells.
