Trials begin on repairs to spinal cord
Print Edition
CHINESE scientists and doctors have begun clinical trials in which they use a collagen complex and stem cells to repair damaged human spinal cord.
Six patients have signed up for the trial and the first surgery was completed last Friday, according to the Chinese Academy of Sciences.
The research was led by Dai Jianwu, a research fellow with the academy’s Institute of Genetics and Development Biology.
The surgery went smoothly and the patient is in a good condition, Dai said.
Dai said the patient was implanted with stem cells and a collagen complex made up of collagen scaffold fibers, also described as collagen tubes, with a protein to support and encourage the growth of neurons.
The collagen complex acts as a bridge for nerves to reconnect and stem cells help tissue recovery, Dai said.
“Previous tests on rats and dogs showed positive results,” he said.
At 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.
