Objective: To evaluate the effects of olfactory ensheathing cell transplantation on functional recovery of rats with complete spinal cord transection.
Data Sources: A computer-based online search of Medline (1989-2013), Embase (1989-2013), Cochrane library (1989-2013), Chinese Biomedical Literature Database (1989-2013), China National Knowledge Infrastructure (1989-2013), VIP (1989-2013), Wanfang databases (1989-2013) and Chinese Clinical Trial Register was conducted to collect randomized controlled trial data regarding olfactory ensheathing cell transplantation for the treatment of complete spinal cord transection in rats.
Selection Criteria: Randomized controlled trials investigating olfactory ensheathing cell transplantation and other transplantation methods for promoting neurological functional recovery of rats with complete spinal cord transection were included in the analysis. Meta analysis was conducted using RevMan 4.2.2 software.
Main Outcome Measures: Basso, Beattie and Bresnahan scores of rats with complete spinal cord transection were evaluated in this study.
Results: Six randomized controlled trials with high quality methodology were included. Meta analysis showed that Basso, Beattie and Bresnahan scores were significantly higher in the olfactory ensheathing cell transplantation group compared with the control group (WMD = 3.16, 95% CI (1.68, 4.65); P < 0.00001).
Conclusion: Experimental studies have shown that olfactory ensheathing cell transplantation can promote the functional recovery of motor nerves in rats with complete spinal cord transection.

Sensory experience during developmental critical periods has lifelong consequences for circuit function and behavior, but the molecular and cellular mechanisms through which experience causes these changes are not well understood. The antennal lobe houses synapses between olfactory sensory neurons (OSNs) and downstream projection neurons (PNs) in stereotyped glomeruli. Many glomeruli exhibit structural plasticity in response to early-life odor exposure, indicating a general sensitivity of the fly olfactory circuitry to early sensory experience.

Spinal cord injuries (SCIs) impact between 250,000 and 500,000 people worldwide annually, often resulting from road accidents or falls. These injuries frequently lead to lasting disabilities, with the severity depending on the injury's extent and location. Emerging research also links SCIs to cognitive impairments due to brain inflammation.

Olfactory ensheathing cells (OECs) and mesenchymal stem cells (MSCs) differentiated towards Schwann-like have plasticity properties. These cells express the Glial fibrillary acidic protein (GFAP), a type of cytoskeletal protein that significantly regulates many cellular functions, including those that promote cellular plasticity needed for regeneration. However, the expression of GFAP isoforms (α, β, and δ) in these cells has not been characterized.

Olfactory ensheathing cell (OEC) transplantation demonstrates promising therapeutic results in neurological disorders, such as spinal cord injury. The emerging cell-free secretome therapy compensates for the limitations of cell transplantation, such as low cell survival rates. However, the therapeutic benefits of the human OEC secretome remain unclear.
