Description

A reliable in vitro system that mimics the neuronal function in the brain is a vital aspect of neurobiology research, and it is the key to successful drug discovery. Neuroblastoma SH-SY5Y cells are commonly used to provide an in vitro model of the neurons.[1,2] SH-SY5Y cells can be differentiated to neurons using different chemical and biochemical reagents.[1–5] Using all-trans-retinoic acid (ATRA), a metabolite of vitamin A, to promote the differentiation of neuroblastoma cells to neurons is a simple and cost-effective way but can not produce mature neurons and the differentiated neurons only survive for few days.[4-7] We developed a method that SH-SY5Y cells gradually differentiated to mature neurons using ATRA. The differentiated SH-SY5Y cells grew on a thin layer of extracellular matrix (ECM), which was secreted into the matrix by the cells. The ECM scaffold allowed the neurons to grow in all dimensions with long neurites, which mimicked the brain network. The neuronal 3D in vitro system was maintained for more than 90 days. To our best of knowledge, this is the first report of survival of the mature neurons for 90 days without passaging. The morphology of SH-SY5Y cells during the differentiation process was monitored by phase-contrast microscopy images. The data provided here contained the detail of the method with the microscopy images that were taken during 100 days of the procedure. References: 1. Forster, J. I. et al.
