All About Stem Cells

What are Stem Cells?

Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types.Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells can either become new stem cells cells or they become specialized stem cells. Specialized stem cells have more specific functions. Some examples include: Blood cells, brain cells, heart muscle, or bone.

Stem Cell Research

Where do Stem cells come from?

Stem cells come from the embryo that are 3-5 days old. An embryo at this stage has about 150 cells. These are pluripotent stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. These cells come from blastocysts that are leftover from infertility treatments that would otherwise be destroyed. This allows embryonic stem cells to regenerate or repair disease, tissue, and organs. For instance, bone marrow stem cells may be able to create bone or heart muscle cells and. These cells are being used in people with neurological or heart disease.

Healthy Life Research Center

The healthy life research center is sponsoring our hospital for stem cell therapy. We are looking for volunteers who will participate in the stem cell therapy. It can be used to cure many diseases such as: Parkinson`s disease and cancer. There are many benefits of this therapy

Potential Stem Cell Therapies

Stem cells are used to cure many diseases. Scientists believe that stem cells can change the future of medicine. The diseases that can be cured with stem cells are Leukemia, Alzheimer`s Disease, Cancer, Parkinson`s disease, ALS, and spinal cord injuries. Stem cells turn into mature cells in bone, tissues, nerves and organs. They regenerate and repair injuries and cure diseases. The first stem cell based therapy was a bone marrow transplant used to treat leukemia. In this experiment, by using radiation the patient got his existing bone marrow destroyed. Then the doner bone marrow is injected into the patient and then the bone marrow stem cells establish themselves into the patient`s bone. Then the patient`s bone marrow will be cured.

Ethical Problems

Many people believe that embryos should not be destroyed to get stem cells. Stem cells destruct the embryos. People believe that embryos should have the right to survive. But this is not true. These embryos can save many lives and it is unethical to stop the research. Some recent experiments have shown that some stem cells can be taken out of an embryo without destroying it.
