Bone marrow Mesenchymal stem cells capable of differentiating into neuronal cells on engineered nanofibrous scaffolds have great potential for bionanomaterial-cell transplantation therapy of neurodegenerative diseases and injuries of the nervous system. MSCs have been the highlight of many tissue engineering studies mainly because of their multipotential properties. We investigated the potential of human bone marrow derived Mesenchymal stem cells (MSCs) for neuronal differentiation in vitro on poly(L-lactic acid)-co-poly-(3-caprolactone)/Collagen (PLCL/Coll) nanofibrous scaffolds. PLCL and PLCL/Coll nanofibrous scaffolds were fabricated by electrospinning process and their chemical and mechanical characterizations were carried out using SEM, contact angle, FTIR, and tensile instrument. The differentiation of MSCs was carried out using neuronal inducing factors including beta-mercaptoethanol, epidermal growth factor, nerve growth factor and brain derived growth factor in DMEM/F12 media. The proliferations of MSCs evaluated by MTS assay showed that the cells grown on PLCL/Coll nanofibrous scaffolds were comparatively higher (80%) than those on PLCL. Scanning electron microscopy results showed that MSCs differentiated on PLCL/Coll nanofibrous scaffolds showed neuronal morphology, with multipolar elongations and expressed neurofilament and nestin protein by immuno-fluorescent microscopy. Our studies on the differentiation of MSCs to neuronal cells on nanofibrous scaffolds suggest their potential application towards nerve regeneration.
