 There are a lot of promises in the stem cell field, but all of them are failing in the clinic. If you read those literatures, they have one thing in common, the cells after transplantation didn't survive. The major reason for that was they were not in the right environment or the micro-environment where they can survive and then do the job they were sent in for. Let's create a micro-environment so that the cells once transplanted, they should be there and then do their job. We specialize there in engineering the matrix in a tissue-specific manner. So the first one we have designed, it is designed for the brain. So we have tuned the stiffness, the porosity of the matrix to a level that matches the compliance of the brain. So when they are cultured in AMGEL, this matrix, they feel that they're in a brain-like environment and that's why they become neuron.
