Introduction: Human neuroblastoma cell line SH-SY5Y is a frequently used experimental cellular model in a variety of neuropsychiatric and neurodegenerative disorders. It is crucial to use a culture protocol that supports the fully differentiation of SH-SY5Y into neuron-like phenotype for the consistency of the results with neurons in vivo. However, a standardized neuronal differentiation protocol for SH-SY5Y cells still does not exist. Numerous differentiation methods have been proposed in the literature, yet SH-SY5Y cells with stronger neuronal characteristics and a more favorable environment for these differentiated cells are required in order to best representation of neurons. Therefore, in the study, we aimed to establish a more successful differentiation protocol for SH-SY5Y cells based on the primary neuron culture technique, which neuronal maturation is very well defined. Methods: In the study, we rearranged previous SH-SY5Y differentiation protocols, combined them with our primary neuron culture protocol and created a robust and reproducible protocol for differentiation of SH-SY5Y. Results: Our proposed “retinoic acid+brain-derived neurotrophic factor (RA+BDNF)-induced 7 days differentiation (conalbumin-on day 4) protocol provided well developed neurites, adequate expression and localization of neuronal and synaptic markers resembling mature neurons. Conclusion: The differentiation protocol we present can enable researchers to obtain satisfactory and properly differentiated SH-SY5Y cells in each independent experiment, achieving the closest possible in vivo results.
