Abstract (original English)

Objectives Cell therapy has provided clinical applications to the treatment of motor neuron diseases. The current obstacle in stem cell therapy is to direct differentiation of stem cells into neurons in the neurodegenerative disorders. Biomaterial scaffolds can improve cell differentiation and are widely used in translational medicine and tissue engineering. The aim of this study was to compare the efficiency of two-dimensional with a three-dimensional culture system in their ability to generate functional motor neuron-like cells from adipose-derived stem cells. Materials and methods We compared motor neuron-like cells derived from rat adipose tissue in differentiation, adhesion, proliferation, and functional properties on two-dimensional with three-dimensional culture systems. Neural differentiation was analyzed by immunocytochemistry for immature (Islet1) and mature (HB9, ChAT, and synaptophysin) motor neuron markers. Results Our results indicated that the three-dimensional environment exhibited an increase in the number of Islet1. In contrast, two-dimensional culture system resulted in more homeobox gene (HB9), Choline Acetyltransferase (ChAT), and synaptophysin positive cells. The results of this investigation showed that proliferation and adhesion of motor neuron-like cells significantly increased in three-dimensional compared with two-dimensional environments. Conclusion
