Transcript of Stem Cell Therapies

Stem Cells What are Stem Cells? Stem cells are biological cells found in all multicellular organisms, that can divide (through mitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In 1968, doctors performed the first successful bone marrow transplant. Bone marrow contains stem cells that can produce all of the different cell types that make up our blood. The existence of stem cells was proven in 1961 by Canadian scientists James Till and Ernest McCulloch. Why Are Stem Cells Important? Stem cells have the potential to treat an enormous range of diseases and conditions that plague millions of people around the world. Their ability to treat so many diseases rests on their unique properties of:
Self-renewal: Stem cells can renew themselves almost indefinitely.
Differentiation: A process by which stem cells develop into specific cell type.
Specialization: A process by which cells are made to do a specific job or function in the body.
Stem cell therapy may eventually treat previously incurable and devastating conditions such as stroke, certain types of Cancer (leukemia, lymphomas, lung cancer), muscular dystrophy, Alzheimer's disease, Parkinson's disease, Diabetes, Heart Disease and spinal cord injuries. Types Of Stem Cells There are two types of stem cells:-
Unlimited stem cells (also known as embryonic stem cells)
Limited stem cells (also known as adult stem cells) Embryonic Stem Cells They can be transformed into many different types of cells.
Embryonic stem cells are able to renew themselves through cell division, which is not seen in specialized cells in the adult body.
Embryonic stem cells can offer an unlimited source of cells that are needed for a variety of medical research areas.
Embryonic stem cells come from eggs that are less than a week old.
Thanks to the process of turning embryonic stem cells into other types such as nerve cells, bone cells and more, there is suddenly the ability to create bones, nerves and other tissues in the human body.
Scientists have come to believe that embryonic stem cells have the ability to be used in the future to treat an untold numbers of diseases and injuries because they can develop into so many different types of cells. Primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found.
Adult stem cells generate bone and muscle cell replacements that have been lost due to disease, age or injury in bone marrow and muscle tissues.
Adult stem cells will always redevelop into the type of tissue that they are found in. If a stem cell is replacing muscles, it will develop into a muscle cell. Adult Stem Cells Stem Cell Therapies HEART
Stem cell researchers envision a variety of potential approaches to fixing the damage done by coronary heart diseases. Among the the possibilities are using stem cells to.....
Generate New Blood Vessels: The new vessels would ensure that the remaining heart tissues get sufficient oxygen, which could prevent further damage to the heart muscle. New blood vessels also would be required in any therapy that involves transplanting or stimulating new muscle tissues.
Grow New Heart Muscle Tissues: Can be used to patch the damaged area of the heart.
Stimulate Blood Vessel Growth Or Repair Of Muscle Tissue: Researchers are experimenting (in animals and in humans) with injecting various kinds of stem cells to prompt this sort of repair activity, or failing that, encourage the remaining healthy tissues to perform better.

Using stem cells to grow new liver tissues.
Developing drugs that spur the liver's stem cells to improve functions. Stem Cell Therapies
Lung cells could potentially be used to repair damage brought on by a variety of pulmonary conditions resulting from a car accident, bullet wound, or sports injury. Studies using such cells have shown promise for tissue repair in mice with acute lung injury. Cancers

Stem cells may also help those who suffer from Parkinson's disorder that can cause tremors, stiffness, and other movement and speech problems. Studies show that embryonic stem cells can give rise to neurons that Parkinson's patients lack. When transplanted into rodents with a Parkinson's-like disorder, those replacement brain cells improved the animals' motor function. What is the difference between adult and embryonic stem cells? An embryonic stem cell potentially can develop into any cell in the body, and an adult stem cell is only able to develop into a specialised tissue cell from which tissue the cell is positioned. What are the two main types of stem cells? The two main types of stem cells are:
Adult Stem Cells
Embryonic Stem Cells
