Neurotrauma injuries are notoriously difficult to deal with both clinically as well as experimentally, as the cellular and molecular events ensuing after injury complicate the neuroinflammatory processes. Spinal cord injuries are further complicated by the formation of scars at the injury sites, which can provide a physical barrier to repair. The lack of effective clinical therapy for spinal cord injury underscores the need for experimental approaches to generate effective therapies. To repair the injury, cell transplantation offers the potential to replace lost cells and create a permissive bridge to promote neural regeneration across the injury site. Olfactory ensheathing cells (OECs), which are the glia of the olfactory nerve, stand apart from other candidate cell types due to their innate natural abilities to manage nerve injury and promote repair and regeneration. This is evidenced by their physiological role in the daily repair and maintenance of the olfactory nerve. Here, we explain their properties in relation to their physiological role and their most relevant cellular attributes, including cellular interactions, phagocytosis, migration, axonal guidance and support, and modulation of neuroinflammation. We highlight some critical drawbacks in the current approaches and identify some ways to address them.
