The Fischer Lab
My research interest is now focused on the biology of neural stem cells (NSC) and their application in restoring connectivity and recovery of function after spinal cord injury. The lab has an history of research in identifying the best strategies for cellular transplantation and in the application of gene therapy methods to introduce therapeutic genes into the injured spinal cord. In the past, we worked with bone marrow stromal cells and genetically modified fibroblasts, but now we use mostly neural stem cells and progenitors (Neuronal-glial) from rodent and human. I am a member of the spinal cord research group.
Project 1 - Transplantation of neural stem cells to reconnect the injured spinal cord (with Dr. Lane).
Project 2 - Spinal Cord Concussion: studying the potential risks of repetitive injury (with Dr. Raghupathi).
Project 3 - Examining the properties and therapeutic potential of glial restricted precursors in spinal cord injury.
Project 4 - Axonal mRNA localization and local protein synthesis in neural progenitor cells in vitro and in vivo in relation to axonal growth and regeneration (with Dr. Twiss).
Project 5 - Regeneration and functional recovery in chronic spinal cord injury.
Project 6 - Developing multifunctional scaffold for treatments of spinal cord injury (with Dr. Galie).
