A. Limitations
So far we have seen a new approach of using stem cells for targeting cancer site and a new concept of
treatment. However it might seem fascinating, it is important to note that significant impediments remain
before the true potential of this novel therapy can be fully realized. Here in this section we are going to
mainly focus on the limitations of neural stem cells esp
