Stem cell injection is a minimally invasive alternative to disc surgery and spinal fusion: an image-guided injection under local anaesthetic, no incision and no hospital stay. Mesenchymal cells, usually from bone marrow, are placed into the painful disc to calm inflammation and support the disc's own repair. Clinical trials from Spain, Iran and Korea and two Chinese meta-analyses report less pain and disability lasting 12 months or more. Our partner clinic in Bangkok has treated more than 1,000 patients, and a doctor reviews your MRI free to recommend the right treatment for you.
What studies suggest
- Some patients report lower pain and disability for 12 months or more
- A few studies describe improved disc hydration on MRI
- Benefits reported for 12 months and longer

Who may be a candidate
- Degenerative disc pain or a contained herniation
- Pain lasting months despite exercise and other care
- People who want to avoid or delay surgery or fusion
Who is not
- Emergencies and progressive weakness: these need surgical assessment
- Severe instability or deformity

Recent research from Asia and beyond
| Country, year | Study | What it found |
|---|---|---|
| China, 2025 | Pooled analysis of randomised trials, Stem Cell Res Ther (PMID 40999526) | Cell therapy significantly reduced pain and disability in chronic low back pain without increasing serious side effects |
| China, 2023 | Meta-analysis, Front Bioeng Biotechnol (PMID 37397969) | Stem cell therapy relieved disc pain and improved disability scores, with low rates of side effects and repeat surgery |
| Iran, 2025 | Phase I trial, Stem Cell Res Ther (PMID 41024309) | Donor bone marrow stem cells injected into painful discs were safe, with promising reductions in pain and better function and quality of life |
| Iran, 2025 | Phase I trial, BMC Musculoskelet Disord (PMID 41034889) | Disc cell transplantation after endoscopic discectomy was safe, with no re-herniation at 2 years |
| Korea, 2023 | Clinical study, Int J Mol Sci (PMID 38069151) | Fat-derived stem cell spheroids were safe; some patients showed less disc protrusion on MRI |
| Japan, 2015 | 3-year clinical study, Eur Cell Mater (PMID 25794529) | Activated disc cell transplantation was safe and may slow further disc degeneration |
| Spain, 2023 | 10-year follow-up, Stem Cell Res Ther (PMID 37038216) | Patients' own stem cells used in spinal fusion were safe, with lasting improvement in pain and disability for 10 years |
Results vary between products and patients, which is why a doctor reviews your MRI first.

Why patients choose stem cells over surgery
- No incision and no general anaesthetic: an image-guided injection under local anaesthetic
- Walk out the same day: most people return to light activity within days
- Keeps your spine moving: no metal, no fused segments, no removed disc tissue
- A fraction of the cost: compared with US disc surgery or fusion
- Works with rehab: you keep exercising while the disc settles
What happens on treatment day
- Assessment: the doctor reviews your MRI, examines you and confirms the treatment plan
- Cell preparation: depending on the plan, cells are prepared from your own bone marrow or fat, or from screened donor tissue
- Injection: under X-ray guidance, the cells are placed into the painful disc or nearby joints
- Rest and review: a short rest, then home or back to your hotel the same day
Recovery and results
Expect some soreness for a few days. Most people are walking normally straight away and resume light activity within the first week, following a gentle rehab plan. Improvement usually builds over weeks to months as inflammation settles and the disc environment improves, so follow-up check-ins at 1, 3 and 6 months help track your progress.
Who is a good candidate
- Degenerative disc pain or a contained disc herniation
- Sciatica or back pain lasting more than a few weeks despite rehab
- People told they need a microdiscectomy or fusion who want a less invasive option first
- People who cannot have, or prefer to avoid, general anaesthetic
When surgery is still the right call
Cauda equina syndrome, rapidly worsening weakness, large free fragments and spinal instability need surgical care. The free MRI review tells you honestly which group you are in.
