Stem cells will now fight Parkinson’s

Stem cells will now fight Parkinson’s

News:

  1. Recently, Japanese scientists announced the first human trial to treat Parkinson’s disease by injecting stem cells into brain, building on an earlier trial on primates.

Important facts:

  1. The research team at Kyoto University plans to inject five million induced Pluripotent Stem (iPS) cells, which have the potential to develop into any cell in the body, into a patient’s brain.
  2. The clinical test will consist seven participants aged between 50 and 69.
  3. The university will monitor the conditions of the patients for two years after the operation.
  4. They also confirmed that the iPS cells had not transformed into tumors during the two years after the implant.
  5. The iPS cells from healthy donors will be developed into dopamine-producing brain cells, which are no longer present in people with Parkinson’s disease.
  6. The clinical trials come after the researchers successfully used iPS cells to restore functioning brain cells in monkeys last year.
  7. In 2014, Riken, a Japanese government-backed research institution, carried out the world’s first surgery to implant iPS cells to treat a patient with age-related macular degeneration (AMD), a common medical condition that can lead to blindness in older people.

9.iPS cells:

  •  iPS cells are created by stimulating mature, already specialised, cells back into a juvenile state — basically cloning without the need for an embryo.
  • These can be derived from the patient, making them less likely to be rejected, while also sidestepping ethical qualms about taking cells from embryos.
  • The cells can be transformed into a range of different types of cells, and their use is a key sector of medical research.
  1. Parkinson’s disease:
  • Parkinson’s disease is a chronic, degenerative neurological disorder that affects the body’s motor system, often causing shaking and other difficulties in movement.
  • Globally, about 10 million people have the illness, according to the Parkinson ’s disease Foundation.
