A. Limitations
So far we have seen a new approach of using stemcells 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 stemcells esp

Enamel
√ Hard and white substance covering the teeth
√ The hardest and most highly mineralized
√ Protects the fragile underlying parts of the teeth
√ Covers the crown and supported by dentin
Component of enamel
√ 96% of enamel : mineral, water, organic material
√ contain two unique classes of proteins amelogenins and enamelins
√ The basic unit of enamel is called
