An example of early applications of stem cell research forging ahead outside the US: "While stem cells have been making news around the world for their potential, and are even being tried on patients, Dr N K Venkataramana, neurosurgeon, BGS Global Hospital in Bangalore, has successfully used the therapy on patients suffering from Parkinson's disease, Alzheimer's, cerebellar degeneration and cerebral palsy. 'I used adult mesenchymal stem cells derived from the bone marrow. They were transplanted into the brain through keyhole surgery. These stem cells multiply and thereby regenerate the damaged areas of the brain. This leads to reactivation of brain cells, resulting in recovery from the disease.' ... He created a state-of-the-art research facility - Advanced Neuro Science Allies - and began his research into the use of stem cell therapy three years ago. 'I picked out authentic mesenchymal stem cells from bone marrow using a marker. The stem cells were purified and tried on animals for safety. Subsequently, we used the therapy on patients. ... Initially, the findings are that we are on the course to a complete cure. All the patients treated so far have a marked decrease in the need for medication. Their symptoms have reduced drastically. They have an increased feeling of well-being and it is obvious that they are recovering. However, there are still some factors to be addressed and understood.'
