What ways might use of adult stem cells be better than the use of embryonic stem cells?
The adult stem cells are better than embryonic stem cells in a very few cases. One way they are better is that the adult stem cells can be transplanted back into the adult patient and grown. The body will not reject its own stem cells.
What is the difference between adherent and suspension cultures?
The way a cell behaves in liquid culture depends on the natural environment of that cell type. Hematopoietic stem cells remain floating in the medium when grown in liquid culture and will not attach to the cell culture vessel. This is known as suspension culture. In contrast, stem cells from most of the body's solid tissues will only grow in culture if they are in contact with a solid surface and other cells. These cells are known as adherent and spread out over the bottom of the vessel as they divide.
Why was the work of the American scientists in 1998 such a breakthrough in stem cell research?
they found a way to obtain stem cells without destroying an embryo - this removed all ethical concerns that were present for the use of embryonic stem cells
How can stem cells be useful?
Stem cells can be used for many things. The one thing that they are being used for now is treating diseases. A stem cell is a cell in the body with no specific function yet. Scientist are trying to discover a way to get the cell to fight cancer. In the UK stem cells have recently cured a man with HIV AIDS.
Why is genetically modifying human embryonic stem cells against the law?
Genetic modification of human embryonic stem cells is against the law because it can give way to unwanted mutations and diseases.
How do stem cells differentiate from other cells?
Stem cells are different from other cells in the body in several notable ways. They can divide and renew themselves many times, whereas other cells are more limited in their divisions. And when those stem cells divide, the new cells can become specialized if necessary. Stem cells have no assigned function in the body, but through the process of specialization, they can take on roles in any of the body's tissues. These type of cells can be derived from human embryos or from certain spots in the adult human body.
What are the difference between ordinary cells and stem cells?
a regular cell is natural ???????? right? A stem cell is a cell that can renew themselves to form other types of cell. Example:Human egg cell/ovum This is an example of a totipotent stem cell. Totipotent stem cells are those cells that can transform into any type of cell. There are many types of stem cells like pluripotent stem cells, multipotent stem cells etc.
Why are stem cells so important in the medical field today?
Stem cells have the ability to differentiate into multiple types of cells. For example, embryonic stem cells can become any cell in the body and hematopoietic stem cells can become any blood cell (red blood cells, myeloid cells, and lymphocytes). They also possess the ability to renew themselves when dividing, meaning that when a stem cell divides, one daughter cell remains a stem cell while the other becomes more specialized. Therefore, the stem cell can theoretically generate an infinite amount of any type of body cells. However, an obstacle in utilizing stem cells is that though scientists have found ways to coax the stem cell to become different cell types, they have been unsuccessful to find a way to make stem cells produce a coherent organ. Meaning that though scientists can make liver cells from stem cells, they can't make an entire liver since the architecture of an entire organ is extremely complex. This is also the reason why we do not yet have laboratory-grown organs for transplantations purposes.
Are stem cells good for someone who has infantile spasm syndrome?
Infantile spasm syndrome is a seizure disorder that affects infants. Some unscrupulous physicians are giving stem cells to infants with the syndrome as a potential \"cure\". However, according to the National Institute of Health Stem Cell Treatment Center, research on stem cells in not advanced enough to represent a cure for this condition. Stem cells have been forced to create brain cells in the laboratory, but this research is a long way from being placed in a living human as a cure for infantile spasm syndrome.
What are the current experimental way that stem cells are being used to treat diseases?
Stem cells can be transformed into other types of cells and replace diseased cells in the body. For example, scientists are working on a way to replace nerve cells damaged by Parkinson's disease.
What are some benefits of researching stem cells?
Cells function in different parts of the body. Stem cells are cells that have not yet formed into a perticular kind of cell; i.e.- red blood cells, white blood cells, skin cells, etc. Scientists can "coax", if you will, the stem cells into any type of cell that they want/need. With stem cells, a person with, say, a blood disorder has the opportunity to go for a stem cell treatment, which would inject the cells into the affected part of the body. The scientists would have, by this point, made the stem cells into the type that the patient needs. With the new cells, the person has a very good chance of having the disorder cured.
Can stem cell therapy stop aging?
what i know of stem cells is that they are like clay. they can replace lost limbs/organs/bones and even skin. in fact the reasons our cuts heal themselves is becuase of adult stem cells in our bodies. If stem cells can repair skin rebuild organs then why not age all together. I think that if we advance stem cell research not to make it easier to GET stem cells but to make ordinary cells turn INTO stem cells, then we can get all the stem cells we need to rebuild our skin, bones, organs, and brain. in fact if we do this we will stop almost all of the diseases bothering us today. so in an awnser to your question "can stem cells stop all aging?" my awnser is WHY NOT maybe you might have to get a supplement of cells and maybe they will stay but either way, i think that eventually they will stop all kinds of age AND damage through quick-repair. course im only 14 and a dreamer/researcher, but everything i have said is FACT.
