to differentiate into the specialized tissues of a whole plant, with the addition of a number of hormones or enzymes. This is an ability known as totipotency.
A callus is often the target of a gene gun for specific DNA insertion experiments.
Callus tissue is of particular use in micropropagation where it can be used to grow genetically identical copies of plants with desirable characteristics.
Discovery of the iPS cell
Expect to solve the problems of ES cells
How to think?
Active factor(protein) in ES cells skin cells
Aug, 2006, Pro. Yamanaka ’s laboratory in Kyoto produced ‘pluripotent cells’
Nov, 2007, the first Human iPS cells
iPS cells are a type of pluripotent stemcell
artificially derived from a differentiated cell,
by inducing a “forced”
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

Dell’s climb to market leadership was the result of a persistent focus on delivering the best possible customer experience. Direct selling, from manufacturer to consumer, was a key component of its strategy (2002).

3. Types of Learning disability
1) Academic Learning disability
These Disabilities are also respectively termed "dyslexia"(Reading Disorder), "dysgraphia"(Writing Disorder), and "dyscalculia"(Mathematics disorder). Youth with learning disabilities most are reading disabled.
