Experimental Protocol of MSC Differentiation into Neural Lineage for Nerve Tissue Regeneration Using Polymeric Scaffolds

The treatment of neurodegenerative diseases is still a challenging grindstone in reconstructive surgeries and regenerative medicine. The retention of mesenchymal stem cells (MSCs) to retain remarkable properties of differentiating into motor neuron-like cells and Schwann cells can prove to be effective in repairing disorders. Moreover, the ultrafine electrospun nanofibers provide a favorable and conducive platform for proliferation and differentiation of MSCs. The development of new 3D culture methods with electrospun scaffolds that closely mimic the physiological niche of cells will help us to understand the functional benefits of MSCs in regeneration process. This article highlights the protocols for isolation of MSCs from rat bone marrow and their subsequent culture on nanofiber scaffolds. Furthermore, this chapter summarizes the various procedures including isolation of the MSCs, their seeding on electrospun nanofibrous scaffolds, and their proliferation and differentiation into neural lineage upon appropriate induction. The materials and preparation of various reagents used at different steps of the protocol are also summarized in detail.
