Comparison of Microtissue Forming Capacity of Sh-Sy5y and Sk-N-as Cell Lines

Abstract

Two-dimensional (2D) cell culture systems are important tools for basic in vitro research. However, they form a thin monolayer structure and poorly mimic the complex in vivo conditions in terms of biochemical signals, cell-cell and cell-extracellular matrix (ECM) interactions. In this study, we performed a comparative study on SH-SY5Y and SK-N-AS neuroblastoma cell lines in terms of their microtissue forming capacity. Both cell lines are commonly used to model neurodegenerative diseases in vitro. Cells were cultured using 3D Petri Dish ® technique. The cells' microtissue forming capacity was observed morphologically and microtissues' size was analized. Results indicate that microtissue forming capacity of SH-SY5Ycell line was better than that of SK-N-AS cell line. SH-SY5Y microtissues can be used as an alternative, scaffold-free in vitro 3D model for neurodegenerative diseases and neuroblastoma research.
