Human tests start on collagen complex to repair spinal cord injury

Chinese scientists and doctors have begun a landmark clinical trial in which they use a collagen complex and stem cells to repair damaged human spinal cord.

Six patients signed up for the trial and the first surgery was completed on Friday, said a statement issued by the Chinese Academy of Sciences (CAS).

The research was led by Dai Jianwu, a research fellow with the CAS’ Institute of Genetics and Development Biology.

Friday's surgery went smoothly and the patient is in a good condition, Dai said.

According to Dai, the patient was implanted with mesenchymal stem cells and a collagen complex made up of collagen scaffold fibers, also described as collagen tubes, with collagen binding brain-derived neurotrophic factor (BDNF), a protein to support and encourage the growth of neurons.

The collagen complex acts as a bridge for nerves to reconnect and mesenchymal stem cells help tissue recovery, Dai said.

"Previous tests on rats and dogs showed positive results," he said.

In this stage, scientists aim to test the safety of surgery and perfect its design, he said.

In the next stage, about 20 to 30 more patients will be involved, he added.

The trial is the first in China and probably the first across the world.

"We hope the research can shed light on this clinical challenge," Dai said.
