Abstract

Background:

A number of clinical trials of olfactory ensheathing cells (OECs) for the treatment of chronic spinal cord injury (SCI) have been carried out all over the world. However, their safety and efficacy have not been basically evaluated. Moreover, there are no uniform standards laid out for the use of optimal source, transplantation method and the dosage of OECs.

Objective:

This study evaluated the source, dose, and route of transplantation of OECs for the treatment of chronic SCI.

Methods:

PubMed, Cochrane Library, EMBASE, CNKI, and Wanfang Data were searched for the clinical studies of OECs in the treatment of chronic SCI on July 2018.

Results:

A total of 30 articles on OECs transplantation for chronic SCI were selected for comprehensive evaluation of OECs sources, doses, and transplantation methods. The efficacy of OECs in the treatment of chronic SCI was evaluated using Review Manager 5.3.

Conclusion:

Fetal OECs are the primary source of cells for the treatment of chronic SCI in OECs, with standardized cell-culture and quality-control processes. Fetal OECs can significantly improve the neurological function of patients with chronic SCI. It is an ideal cell therapy for neurorestoration. However to explore more precise and minimally invasive treatment options are required in the future.
