Research Program


Outline of  Karimi research program:

    Karimi's laboratory offers training opportunities for graduate students and postdoctoral fellows in neurosciences and stem cell research. Our research focuses on promoting neural repair and regeneration after injuries to the central nervous system with special interest in spinal cord injury (SCI) and myelin disorders. We  use neural stem cell-based therapeutic approaches in preclinical models of SCI and myelin deficiency. Neural stem cells hold tremendous promise for repairing central nervous system injuries since they have multipotential abilities to replace all damaged neural cells and the potential to provide a supporting environment for regeneration.

    Using complementary in vivo and in vitro approaches, our research team strives to understand how the properties of these stem cells are modulated within the microenvironment of SCI and how they can be efficiently recruited to replace lost neurons and oligodendrocytes. This knowledge is vital to develop new stem cell therapies to functionally enhance spinal cord regeneration.  We specifically focus on developing repair strategies to optimize the replacement of oligodendrocyte, axonal protection and remyelination.

    In our laboratory, we employ an array of advanced approaches in neuroscience and stem cell research that include in vivo spinal cord injury and micro-surgical techniques, stem cell/neural tissue culture, pharmacological drug delivery, cellular, biochemical and molecular techniques, genetic manipulations, fluorescence/confocal imaging, bioengineering approaches, live animal imaging and functional/neurological analyses.
Our research has high translational implications in the fields of spinal cord injury and regenerative medicin
