celltype. For plantcells, enrichment with nitrogen, phosphorus, and potassium is especially important. Water is provided as a constituent part of the gel media.
Uses
A plantcell callus consists of somatic undifferentiated cells from an adult subject plant.
A callus is not necessarily genetically homogeneous because a callus is often made from structural tissue, not individual cells. Nevert

1908 - The term "stem cell" was proposed for scientific use by the Russian histologist Alexander Maksimov (1874–1928) at congress of hematologic society in Berlin. It postulated existence of haematopoietic stem cells.
1998 - James Thomson and coworkers derive the first human embryonic stem cell line atthe University of Wisconsin–Madison.

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 importantto 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
