Stem Cell Research
Stem cells are the Best and can save a life
What are stem cells?
stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle or bone. No other cell in the body has the natural ability to generate new cell types.(http://www.mayoclinic.org/tests-procedures/stem-cell-transplant/in-depth/stem-cells/art-20048117)
why do stem cell come from?
Researchers have discovered several sources of stem cells:
Embryonic stem cells
Adult stem cells.
- Adult cells altered to have properties of embryonic stem cells (induced pluripotent stem cells).
- Perinatal stem cells
Potential stem cell therapies
The first trials for embryonic stem cells have only just begun. Results from those won't be available for many years, once the necessary clinical trials are completed showing that the therapies are safe and that the work in treating disease. The only stem cell-based therapy currently in use is in bone marrow transplantation. Blood-forming stem cells in the bone marrow were the first stem cells to be identified and they are now the first to be used in the clinic.
The blood-forming stem cell is the component of bone marrow that is therapeutic in a bone marrow transplant. With the isolation of pure blood-forming stem cells it is now possible to transfer just the cells that are needed to replace the bone marrow. The cells migrate to appropriate bone marrow where they self-renew and rebuild the entire blood system.
Transplants of blood-forming stem cells have been used successfully in cancer treatments, and research suggests that they will be useful in treating autoimmune diseases and in helping people tolerate transplanted organs.
There are other therapies based on adult stem cells still in clinical trials. Until those trials are complete we won't know which stem cells are most effective in treating different diseases.
Issues in stem cell research
What I think of stem cells
I think stem cells are good things and can help solve a lot of problems. Some other applications of stem cells are being investigated in clinical trials, including the use of stem cells to regenerate damaged tissues – such as heart, skin, bone, spinal cord, liver, pancreas and cornea – or to treat blood or solid-organ cancers. The majority of these trials are using mesenchymal stem cell, which are derived from sources such as fat tissue, bone marrow and connective tissue. A small proportion of the trials are using blood cells.
