Stem cells therapies to treat Parkinson.s disease 2

Adults stem cell can be isolated from bone marrow, the liver, muscle, the brain, fat and other tissues. These cell can provide fewer different types od differentiated cells. Though so far stem cells have not cure any condition, doctors have successfully used them in blood and marrow transplants for more than thirty years. These transplants are used in the treatments of leukaemai and lymphoma to sustain life after chemotherapy and radition.

Experimentally they are used to replaced a defective immune systems in some inherited immune disorders, and to replace an immune system turned against itself, such as in some autoimmune disorders.

In future stem cells might be used to replace disease cells. If stem cells could be directed differentiate into specific cell types, they could treat Parkinson's disease, spinal cords injuries, burns, Alzheimer's arthritis, disorders of bone development and other conditions.

Stem cells therapies to treat Parkinson.s disease

Stem-cell research is a new frontier in medicine. REsearchers are seeking ways to create stem-cell based therapies to treat or cure illnesses such as Parkinson's disease, Alzheimer's, diabetes, heart disease and spinal cord injuries. But the real world application, if they occur are years away.

Stem cells are difference from other cells in the body. When most cells divide, they produce two identical dauther cells, not so with stem cells, Some stem cells become specialised for example cells of the skin or heart muscle and some remains stem cells, replenishing the stem cell pool. Because some stem cells change into specialised cells, researchers believe they may be useful in repairing tissues damaged by disease, aging or injury. Sten cells are not all the same. Different stem cells can be derived from embryos, umbilical- cord blood and the plancenta and adult tissues.

Embryonic stem cells come from human eggs fertilised in vitro out of the body as part of infertility treatment. Some Embroyos may remains after a women become pregnant, and are provided for research with the concent of the donors. Embryonic stem cells can differentiate into any type of cell in the body.
