Stem cells for spinal cord injury: hope versus evidence

Why the spinal cord is the hardest tissue to repair

Quick answer

Spinal cord injury produces a glial scar that physically and chemically blocks nerve regrowth. Cell research therefore aims to lower inflammation, limit fibrosis and create a more permissive environment for connections — not to splice severed nerves. It remains investigational and case-by-case.

The glial scar that blocks regrowth

Completeness of injury is the single biggest predictor. Patients with preserved partial function (incomplete injury) have markedly better recovery prospects than those with a complete lesion, and that should be explained before any decision.

Delivery routes and their risks

Delivery routes differ — intravenous, intrathecal, or direct injection at the lesion during surgery — and each carries its own risk. Local injection in particular is invasive and belongs only in centres with a neurosurgical team.

Rehabilitation that actually works

What is proven to help is intensive rehabilitation, pressure-sore prevention, bladder and bowel management and neuropathic pain control. Families should invest there first, then consider adjunct options with full information.

Frequently asked questions

  • Is walking again possible?

    It depends chiefly on lesion level and completeness. No method can guarantee it, and outcome promises should be treated with suspicion.

  • Sooner or later?

    A medical team must judge: the acute phase offers more opportunity but also more risk than the chronic phase.
