Abstract: Olfactory ensheathing cells (OECs) are a novel type of glial cell that can perform and promote many neurorestorative processes in vivo after transplant. To date, dozens of preclinical and clinical studies have confirmed that OECs have unique restoring effects in animal models and human subjects with neurological degeneration or damage, such as spinal cord injury, stroke, cerebral palsy, traumatic brain injury, and motor neuron disease (amyotrophic lateral sclerosis). To ensure the safety and effectiveness of clinical applications utilizing this type of cell, it is important to standardize cell-culture and quality-control processes. Based on a comprehensive review of published clinical studies, as well as existing methods of OEC culture and quality control currently utilized by hospitals and biomedical enterprises, the Chinese Association of Neurorestoratology has developed a set of standards for the culture and quality control of olfactory ensheathing cells for use in clinical applications. These guidelines include standardized training and management procedures for laboratory operators; standardized use and management of materials and equipment; standardized collection, culture, and proliferation of OECs obtained from fetal olfactory bulbs; standardized management for cell preservation, transport, and related safeguard measures; and the standardization of a clean environment, routine maintenance, and related tests and examinations. Our goal in publishing this set of standards is to promote the worldwide safety, effectiveness, and replicability of utilizing OECs obtained from fetal olfactory bulbs for neurorestorative clinical application.
