A fascinating new treatment may provide hope for those who have been told they may never walk again. After all, that's what doctors said to Darek Fidyka of Poland after a knife attack in 2010 left him paralyzed from the chest down. Yet now, two years after undergoing an experimental procedure, Fidyka is able to walk with aid of a frame.
BBC News' Fergus Walsh explains how a team of British and Polish doctors reignited Fidyka's mobile fire:
"The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell.
OECs act as pathway cells that enable nerve fibres in the olfactory system to be continually renewed."
These regenerative cells were first removed from the patient's nasal cavity, allowed to grow in culture, and then implanted into his spinal cord. As Walsh writes, the scientists who have monitored Fidyka believe the OECs helped reconnect the nerves in his spine and set him on the road to recovery. MRI scans show that gaps in the spinal cord fully recovered after the procedure.
