In a world first, Japanese neurosurgeons have implanted a Parkinson’s disease patient with “reprogrammed” stem cells – and if the treatment continues to show success, then it could be sold to other patients as early as 2023.

The devastating disease is caused by a lack of cells in the brain that produce dopamine, which is an essential neurotransmitter in the brain. The decrease in dopamine causes trembling, a decline in motor functions, and – if the disease progresses – dementia.

Scientists from Kyoto University in Japan are attempting to reverse the disease by using donated adult stem cells that have been taken from another patient so they can then “reprogram” them into embryonic cells. These reprogrammed embryonic cells, which are called induced pluripotent stem (iPS) cells, can then be developed into dopamine-producing neurons.

Some scientists have expressed concern that the application of these cells would result in malignant tumors, but the research team received permission for the first-of-its-kind clinical trial back in July after they successfully used iPS cells to restore normal brain function in monkeys without any sign of tumors over the course of their 2-year study.

According to Nature, the research team injected 2.4 million of the special cells into the brain of a Parkinson’s patient in his 50s – and in the weeks following the 3-hour procedure back in October, “the patient [has been] doing well and there have been no major adverse reactions so far,” says scientist Jun Takahashi.

If the patient continues to respond well to the therapy, then the team will implant another 2.4 million cells into the patients brain in 6 months. After that, they plan on testing the therapy on 6 more patients by the end of 2020 to prove its efficacy and safety.

The researchers hopes to have enough evidence to make the treatment commercially available to patients by 2023 as a fast-tracked therapy for neurodegenerative diseases in Japan.

  1. This is actually happening in the US as well. They are calling it biocell regenerative medication, It uses your own stem cells & stromal cells to heal your body. Here is a breif description : Carefully and accurately placed, these elements provide the most important growth factors and signal proteins (from platelets) and cells which have reparative abilities, each critical to the natural wound healing process. By providing these in a concentrated form and accurately placed (ultrasound guidance) insures the best chance for you to heal and regenerate damaged and aging tissues of your body. Uses in helping arthritis, back pain, leg pain, bone and joint problems, sport injuries, shortening post-surgery healing.

    As far as I know they are currently testing on MS, Parkinsons, COPD, etc. The difference here would be that these are not directly injected into the brain as the above researchers are doing, Most of this is done intravenously as to avoid the potential complications of injecting into the brain. From what I am told the result so far are looking very promising.
