Japanese government approved the 1st stem cell trial produced from the body of patient.
The stem cells could become any of the other body part- nerve or bone or skin – and they’re touted as future of the medicine.
The researchers who are in Japan would use these cells for attempt to cure one blindness form, the macular degeneration that is age-related.
This announcement was explained as major step ahead for the research in this field.
There’re already trials being held using the stem cells which are extracted from embryos. Though this is controversial ethically and cells won’t match patient’s tissues, so there’s rejection risk.
Pluripotent and induced stem cells, anyway, are made through coaxing one sample of patient’s skin so that it become the stem cells and so there need to be no rejection risk.
Saving the sight?
Norihisa Tamura, the health minister of Japan has said that cells could be now tested in the patients.
This trial would be run by Riken Center for Developmental Biology and the Institute of Biomedical Research and Innovation Hospital located in Kobe.
In the beginning, 6 patients would receive the cell transplants to see whether the procedure could have their damaged vision restored.
Expert of regenerative medicine in University College London, Prof Chris Mason said that it was expected, though it was one major step ahead. They’re useful for basically 2 main reasons: first is that they’re from patients themselves that is why rejection chance is much reduced and there’re ethical considerations that they don’t have baggage that comes with the stem cells of embryo. Towards down side, we’re one decade behind where science is concerned. Stem cells that are pluripotent and induced were discovered quite later, so we happen to be behind on safety.
Prof Shinya Yamanaka, in 2012, shared Nobel prize that was for physiology or medicine for the discovery he made that adult human’s tissue can be for sure coaxed back in the state of stem cell.
