Stem Cells-The Promise of Life-Threatening Injuries and Deadly Diseases ?
Nowadays there are several STEM CELL THERAPIES which are used to treat incurable diseases and save people from these life threatening diseases.

• Adult Stem Cell Transplant: Bone Marrow Stem Cells
• Adult Stem Cell Transplant: Peripheral Blood Stem Cells
• Umbilical Cord Blood Stem Cell Transplant

Adult Stem Cell Transplant: Peripheral Blood Stem Cell Transplant
While most blood stem cells reside in the bone marrow, a small number are present in the bloodstream. These multipotent peripheral blood stem cells, or PBSCs, can be used just like bone marrow stem cells to treat leukemia, other cancers and various blood disorders. Since they can be obtained from drawn blood, PBSCs are easier to collect than bone marrow stem cells, which must be extracted from within bones. This makes PBSCs a less invasive treatment option than bone marrow stem cells. PBSCs are sparse in bloodstream; however, so collecting enough to perform a transplant can pose a challenge.

Umbilical Cord Blood Stem Cell Transplant

Newborn infants no longer need their umbilical cords, so they have traditionally been discarded as a by-product of the birth process. In recent years, however, the multipotent-stem-cell-rich blood found in the umbilical cord has proven useful in treating the same types of health problems as those treated using bone marrow stem cells and PBSCs.
Umbilical cord blood stem cell transplants are less prone to rejection than either bone marrow or peripheral blood stem cells.. Also, because umbilical cord blood lacks well-developed immune cells, there is less chance that the transplanted cells will attack the recipient’s body, a problem called graft versus host disease.
Both the versatility and availability of stem cells makes them a potent resource for transplant therapies and the promise to treat life threatening diseases.
