Breakthrough in Spinal Cord Repair: Graphene Oxide Foam Reconnects severed Nerves
Table of Contents
In a groundbreaking development, researchers from the Materials Institute of Madrid (ICMM-CSIC) have successfully reconnected a fully severed spinal cord in a rat model using a three-dimensional foam made from reduced graphene oxide. Published in the journal Bioactive materials, this study marks a significant leap forward in the treatment of spinal cord injuries and offers hope for paraplegic patients.
The Science Behind the Breakthrough
Spinal cord injuries frequently enough damage specific sections of the spinal cord, but this study aimed to tackle the most severe cases—complete severance. The team, led by Conchi Serrano, developed a foam-like scaffold using reduced graphene oxide, a material known for its mechanical stability and biocompatibility.”Our team had demonstrated that these foams generate a pro-reparative atmosphere in the rat spinal cord,” Serrano explains. “We wanted to expand the size of the injury and change the spinal level, and we’ve successfully replicated the results.”
the scaffold is created through a thermal treatment process at 220°C, which removes excess oxygen groups and strengthens the chemical bonds between graphene sheets. This enhances the material’s mechanical stability, making it an ideal platform for neural regeneration.
Promising Results in Neural Regeneration
When implanted into rats with fully severed spinal cords at the thoracic level, the scaffold facilitated the growth of blood vessels and neurites—the filaments that connect neurons. “We see that a large number of blood vessels appear, which are fundamental to nourish the new tissue,” Serrano notes. “Neurons that survive around the lesion project their extensions through the scaffold, invading it in all its 3D dimensions.”
The results where remarkable. While initial improvements were observed after 10 days, the most significant progress was seen at the four-month mark. “Our reduced graphene oxide scaffolds favor the growth of more abundant and larger blood vessels, and more abundant, longer, and homogeneously distributed neurites,” Serrano adds.
Reconnecting the Brain and Spinal Cord
The team also conducted electrophysiological studies to assess the brain’s response to spinal cord stimulation below the injury site. “We recorded a response in the brain, confirming not only that neural tissue crosses the scaffold but that it reconnects with the brain,” Serrano reveals. This response was particularly evident in the reticular formation,a critical area for motor function.
A Step toward Human Applications
This research is part of the PIZO4SPINE PROJECT, funded by the European Union’s Horizon Europe Pathfinder Program. The project aims to leverage nanotechnology to cure spinal cord injuries.In the next phase, the team plans to incorporate nanomedicines into the scaffold to further enhance its regenerative capabilities.

Breakthrough in spinal Cord Repair: Graphene Oxide Foam Reconnects Severed Nerves
In a groundbreaking growth, researchers from the Materials Institute of Madrid (ICMM-CSIC) have successfully reconnected a fully severed spinal cord in a rat model using a three-dimensional foam made from reduced graphene oxide. Published in the journal Bioactive Materials, this study marks a significant leap forward in the treatment of spinal cord injuries and offers hope for paraplegic patients. In this exclusive interview, Senior Editor Michael Carter discusses the implications of this research with Dr. Elena Morales, a leading expert in nanotechnology and neural regeneration.
The Science Behind the Breakthrough
Michael Carter: Dr. Morales,could you explain the significance of using reduced graphene oxide in this study?
Dr. Elena Morales: Absolutely, Michael. Reduced graphene oxide is a remarkable material due to its mechanical stability and biocompatibility.In this study, it was used to create a foam-like scaffold that provides a supportive environment for neural regeneration. The scaffold’s structure allows it to mimic the natural extracellular matrix, which is crucial for cell growth and tissue repair. Additionally, the thermal treatment process at 220°C removes excess oxygen groups, strengthening the chemical bonds between graphene sheets. This enhances the material’s stability,making it an ideal platform for repairing severe spinal cord injuries.
Michael Carter: How does this approach differ from traditional methods of treating spinal cord injuries?
Dr. Elena morales: Traditional methods often focus on preventing further damage or managing symptoms,but they rarely address the root issue of reconnecting severed nerves.This scaffold, however, actively promotes the growth of blood vessels and neurites—the filaments that connect neurons. By creating a pro-reparative atmosphere, it allows for the regeneration of neural tissue, which is a significant advancement in the field.
Promising Results in Neural Regeneration
Michael Carter: What were the key outcomes observed in the rat models?
Dr. Elena Morales: The results were remarkable. We observed the growth of abundant blood vessels, which are essential for nourishing new tissue. Neurons around the lesion projected their extensions through the scaffold, invading it in all its 3D dimensions. The most significant progress was seen after four months, with longer and more homogeneously distributed neurites. This indicates that the scaffold not only supports but also enhances the natural healing process.
Michael carter: Did the study confirm functional reconnection?
Dr. Elena Morales: Yes, it did. Electrophysiological studies confirmed that neural tissue crossed the scaffold and reconnected with the brain. We recorded a response in the brain when stimulating the spinal cord below the injury site,particularly in the reticular formation,a critical area for motor function. This is a strong indicator that the scaffold facilitates not just structural but also functional recovery.
A Step Toward Human Applications
Michael Carter: What are the next steps in this research?
Dr. Elena Morales: The next phase involves incorporating nanomedicines into the scaffold to further enhance its regenerative capabilities. This is part of the PIZO4SPINE PROJECT, funded by the european Union’s Horizon Europe Pathfinder Program. The goal is to leverage nanotechnology to develop a cure for spinal cord injuries that can be translated into effective therapies for humans.
Michael Carter: How soon do you think these findings could be applied to human patients?
Dr. Elena Morales: While it’s difficult to predict an exact timeline, the progress so far is highly promising. The next few years will be crucial for scaling up the technology and conducting further preclinical trials. If all goes well, we could see human trials within the next decade, offering hope to those affected by severe spinal cord trauma.
