The breakthrough sidestepped the embryo controversy, offering researchers an unlimited supply of stem cells. Yamanaka shared the 2012 Nobel Prize in Physiology or Medicine for reprogramming mature cells into what are now called induced pluripotent stem cells, or i PS cells.
Still, the march toward new treatments has been halting. Yamanaka directs Kyoto University’s Center for i PS Cell Research and Application. Masayo Takahashi and her colleagues at the Riken Center for Developmental Biology had great success using i PS cells to treat macular degeneration.
I think the science has moved too far ahead of talk of ethical issues. Twenty-five years later, just two years ago, scientists developed a very effective cure.
When we succeeded in making i PS cells, we thought, wow, we can now overcome ethical issues of using embryos to make stem cell lines. So getting an ethical consensus is extremely important. He injured his leg in the factory when I was in junior high.
In the two decades since, the prolific cells have been a fixture of his career.
The biologist, now at Columbia University in New York City, has used them to explore how DNA from adult cells can be reprogrammed to an embryonic state, and to tackle questions about the development and treatment of diabetes.That is called direct cellular reprogramming, and it might work better than i PSC if, say, we need to replace all the cartilage in an elderly person’s knee.But i PS would probably be the choice if we are treating a younger person who only has a small lesion in the knee.We could make good cartilage from i PSCs and transplant that purified cartilage to that small lesion. What are your biggest concerns about the future of stem cell treatments? But it took 25 years.i PS cells are only 10 years old. Well, we realized that it would take a great deal of time and would be unrealistically expensive to carry out the deep sequencing and animal studies for each patient’s cells. We can help just a small portion of patients by stem cell therapy. Parkinson’s disease is caused by failure of very specialized brain cells that produce dopamine.How many compatible donor cell lines do you expect will be needed to cover the Japanese population? One particular line — just one — can work for 17 percent of the Japanese population. For example, target diseases for cell therapy are limited. Heart failure is caused by loss of function of cardiac heart cell. We can make that one type of cell from stem cells in a large amount, and by transplanting those cells, we should be able to rescue the patient.Five years later, a Kyoto University scientist, Shinya Yamanaka, and his graduate student, Kazutoshi Takahashi, re-energized the field by devising a technique to “reprogram” any adult cell, such as a skin cell, and coax it back to its earliest “pluripotent” stage.From there it can become any type of cell, from a heart muscle cell to a neuron.“They will lead to unprecedented discoveries that will transform life.I have no doubt about it.”Embryonic stem (ES) cells provide unparallelled information on early development.
