Research Abstract
Pre-clinical and translational work from my laboratory has directly supported an IND filing for an FDA-approved phase I trial of human neural stem cells in the myelination disorder Pelizaeus-Merzbacher disease (PMD), and a phase I/II clinical trial for human neural stem cells in thoracic spinal cord injury (SCI). These translational milestones reflect over 15 years of work from my laboratory on human-derived neural stem cell (hNSC) populations and spinal cord injury mechanisms. In these studies, we have investigated the intrinsic and extrinsic factors defining the migration and differentiation potential of these cells both in vitro and after transplantation into the spinal cord. In parallel, we have investigated nontraditional roles for the innate inflammatory system in the pathophysiology of spinal cord injury, mechanisms controlling stem cell fate and migration, and potential for implanted biomaterial scaffolds to provide an environment supporting robust axonal regeneration. This work has led us to the discovery of a role for complement C1q and C3a/C3b as single molecules in the CNS, controlling mouse and human NSC behavior, including self-renewal. Recently, we have extended these novel findings to investigate whether endogenous NSC in the subventricular and subgranular zone brain neurogenic niches share common mechanisms with the hNSC we have used in transplantation. These studies have identified a key role for both innate immune cells and autocrine / paracrine complement signaling in survival, self-renewal, and differentiation in the adult brain, as well as a role for these proteins in age-related neurogenesis declines and glioblastoma.
