THOMAS AND COLLEAGUE ADVANCE A REVOLUTIONARY MEDICAL THERAPHY
Stem cell therapy is the treatment of various disorder by using stem cells it is use to potentially treat more than 80 disorder, including degenerative and neuromuscular disorder hematopoietic disorder like storage disorder, leukemia affect the bone marrow and it is overcome by stem cell from Donor are known to reconstitute the defective bone marrow.
Stem cells are cells that have
the ability to differentiate into a diverse range of cell types, creating the
potential for the cell to be used to grow replacement tissues. American
development biologist James Thomson from the University of Wisconsin School of
medicine, won the race to isolate and culture human embryonic stem cells. On
November 6, 1998 the journal science published the results of Thomas's
research, describing how he used embryos from clinics (donated by couple who no
longer needed them), and developed way to extract stem cell and keep them
reproducing indefinitely
With the ability to
develop into any one of the 220 cells types in the body, stem cell hold great
promise for treating a host of debilitating illnesses, including diabetes,
leukemia, Parkinson's diseases, and spinal cord injury. They also provide
scientists with models of human disease and new way of testing drugs more
effectively in human organisms .but for all the hopes invested, progress has
been slow .it has not helped that the stem cell research has been steeped in
controversy, with different group questioning the ethics of harvesting stem
cell from human embryos.
In 2007 Thomas and Shinya
Yamanaka, from Kyoto University, Japan, both groups used just four genes to
reprogram human skin cells. Their work is being heralded as an opportunity to
overcome problem including the storage of human embryonic stem cell and
restriction on U.S. Federal funding for research
since 1988, therapy using stem
cell, including those from bone marrow and umbilical cords has been
successfully used to treat a number of life threatening diseases. It
become one of the most exciting area of medicine and in field of medical
science
