Write a note on the principles of stem cell therapy and latest advancements
in this field.
Stem-cell therapy is the use of stem cells to treat or prevent a disease or
Bone marrow transplant is the most widely used stem-cell therapy, but some
therapies derived from umbilical cord blood are also in use. Research is
underway to develop various sources for stem cells, and to apply stem-cell
treatments for neurodegenerative diseases and conditions such as diabetes, heart
disease, and other conditions.
Stem-cell therapy has become controversial following developments such as the
ability of scientists to isolate and culture embryonic stem cells, to create
stem cells using somatic cell nuclear transfer and their use of techniques to
create induced pluripotent stem cells. This controversy is often related to
abortion politics and to human cloning. Additionally, efforts to market
treatments based on transplant of stored umbilical cord blood have been
Some of its applications are :
a. regeneration of lost limbs or other bodily organs
b, to suppress the expression of some genes, particularly for preventing
cancerous genes to develop
c. For treatment in diabetes, health loss, teeth replacement etc.
d. Now in UK, researches have explored possibility of treating foetuses by stem
cell therapy to remove genital defects.
But use of stem cell therapy has been surrounded by ethical issues also:
a. use of embryonic blood for stem cells, results in their manipulation causing
b. Stem cell therapy is also considered ideal for human cloning .
Thus, given the immense potential of stem cells, world medical community should
evolve ethical guidelines for the development and regulation of stem cell
