The Times of India reports on early results in using stem cells to repair nephritis: Indian researchers claim "to have pioneered stem cell therapy for the first time on patients suffering from acute and chronic nephritis which may end in kidney failure. Nephritis is an early kidney disease which in many cases is chronic and becomes resistant to drugs. The disease may lead to kidney failure. Since we are doing stem cell therapy for kidney transplant patients, we decided we should also try using it to prevent kidney failure as well ... The stem cell therapy for nephritis has been done in two patients. ... The bone marrow and mesenchymal stem cells were delivered directly into the kidneys through [an artery] so as to help the organ repair the damage. ... This treatment is at experimental stage as we are still working out the dose of stem cells per kg that a patient may need for best results." Both patients greatly improved, to be point of being able to claim a cure, but as noted this is very early stage work. Still, India is not the US; while its regulators are excessive, they are nowhere near as bad as the FDA. So expect to see medical tourism for this therapy within the next year or two.
