The experts said they were particularly concerned about a firm in Germany called XCell-Center and about Beike, which offers stem cell treatments for a range of conditions including brain injury, cerebral palsy, multiple sclerosis, spinal cord injury and optic nerve damage.
- A spokesman for XCell said in a statement that its stem cell preparations are made from bone marrow and intended for "autologous" use, or use by patients from whom they came.
- Beike Biotech said in a statement that all its stem cells are administered by experienced physicians who work in and for leading hospitals in China.
Stem cells are standard treatments for leukemias and a few other genetic diseases, but their use in treating other conditions such as Parkinson's, spinal injury or optic nerve damage is as yet unproven.
