A Stem Cell In An Animal Divides By Mitosis. Which Statement Is True About The Daughter Cells?

What Are Stem Cells?

Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells. In some cases, they can too fix damaged tissues. Researchers believe that stalk cell-based therapies may one day exist used to treat serious illnesses such as paralysis and Alzheimer disease.

Types of stem cells

Stem cells are divided into 2 main forms. They are embryonic stem cells and developed stem cells.

Embryonic stem cells. The embryonic stem cells used in research today come from unused embryos. These upshot from an in vitro fertilization process. They are donated to science. These embryonic stem cells are pluripotent. This means that they can turn into more than one type of cell.

Adult stem cells. There are 2 types of adult stem cells. One type comes from fully adult tissues such as the brain, skin, and bone marrow. There are only small numbers of stem cells in these tissues. They are more likely to generate merely sure types of cells. For instance, a stem cell that comes from the liver will only brand more than liver cells.

The second blazon is induced pluripotent stem cells. These are developed stalk cells that have been changed in a lab to be more like embryonic stem cells. Scientists first reported that human stem cells could be changed in this way in 2006. Induced pluripotent stem cells don't seem to exist unlike from embryonic stalk cells, only scientists take not nevertheless found one that can develop every kind of prison cell and tissue.

Stalk cells in medicine

The only stalk cells now used to treat illness are hematopoietic stem cells. These are the blood prison cell-forming adult stem cells found in bone marrow. Every type of claret cell in the os marrow starts as a stalk cell. Stem cells are immature cells that are able to make other blood cells that mature and function as needed.

These cells are used in procedures such every bit bone marrow transplants. These help people with cancer make new blood cells after their own hematopoietic stalk cells have been killed by radiation therapy and chemotherapy. They may also exist used to treat people with conditions such as Fanconi anemia. This is a claret disorder that causes the body'south bone marrow to fail.

Stem cells may help your health in the futurity in many ways and through many new treatments. Researchers think that stem cells volition be used to help create new tissue. For example, i day healthcare providers may be able to treat people with chronic heart disease. They can do this past growing salubrious heart muscle cells in a lab and transplanting them into damaged hearts. Other treatments could target illnesses such as blazon 1 diabetes, spinal cord injuries, Alzheimer affliction, and rheumatoid arthritis. New medicines could also be tested on cells made from pluripotent stem cells.

Challenges in stem cell research

Stem cells need much more written report before their apply tin be expanded. Scientists must first larn more about how embryonic stem cells develop. This will help them understand how to control the type of cells created from them. Another challenge is that the embryonic stalk cells available today are likely to exist rejected by the torso. And some people find it morally troubling to use stem cells that come up from embryos.

Scientists also face up challenges when using adult pluripotent stalk cells. These cells are hard to grow in a lab, and then researchers are looking into ways to improve the process. These cells are also found in small amounts in the torso. At that place is a greater chance that they could contain Deoxyribonucleic acid problems.

Clinical trials that use stem cell therapies are currently being done in the U.Due south. If y'all are interested in trying this therapy to treat a certain condition, ask your healthcare provider how to find out near trials available in your expanse.
