Introduction: Transplantation of stem cells with a nanofibrous scaffold is a promising approach for spinal cord injury therapy. The aim of this work was to differentiate neural-like cells from placenta-derived mesenchymal stem cells (PDMSCs) using suitable induction reagents in three (3D) and two dimensional (2D) culture systems.
Methods: After isolation and characterization of PDMSCs, the cells were cultivated on poly-L-lactide acid (PLLA)/poly caprolactone (PCL) nanofibrous scaffold and treated with a neuronal medium for 7 days. Electron microscopy, qPCR, and immunostaining were used to examine the differentiation of PDMSCs (on scaffold and tissue culture polystyrene [TCPS]) and the expression rate of neuronal markers (beta-tubulin, nestin, GFAP, and MAP-2).
Results: qPCR analysis showed that beta-tubulin (1.672 fold; P ≤ 0.0001), nestin (11.145 fold; P ≤ 0.0001), and GFAP (80.171; P ≤ 0.0001) gene expressions were higher on scaffolds compared with TCPS. Immunofluorescence analysis showed that nestin and beta-tubulin proteins were recognized in the PDMSCs differentiated on TCPS and scaffold after 7 days in the neuroinductive differentiation medium.
Conclusion: Taken together, these results delegated that PDMSCs differentiated on PLLA/PCL scaffolds are more likely to differentiate towards diversity lineages of neural cells. It proposed that PDMSCs have cell subpopulations that have the capability to be differentiated into neurogenic cells.
