Mutations have been observed in stem cells cultured for a number of generations, and some mutated stem cells have been observed to behave like cancer cells. Cultured stem cells could be contaminated with viruses which would be transferred to a patient.
Can you cure a disease with antibiotics?
Some diseases can be treated with antibiotics, but not all can be cured. Vaccinations allow protection against specific diseases, but the level of protection depends on the amount of people vaccinated.
Can embryonic stem cells differentiate?
Embryonic stem cells can differentiate into a wider range of cell types, but are difficult to obtain and their use raises ethical challenges. The best source is the five-day-old embryo. Adult stem cells will differentiate into a narrower range of cell types.
Why are stem cells important?
Stem cells may therefore be very useful as a therapy for diseases in which organs are damaged or where the immune system is too active. Some types of stem cells are already used for therapy, such as the hematopoietic (blood) stem cells, which are used for the treatment of bone marrow cancer.
How do stem cells work?
Specialized types of stem cells have the ability to stop immune responses. Stem cells may therefore be very useful as a therapy for diseases in which organs are damaged or where the immune system is too active. Some types of stem cells are already used for therapy, such as the hematopoietic (blood) stem cells, which are used for the treatment of bone marrow cancer. The use of other types of stem cells is currently being studied in the laboratory and in experimental therapies. Researchers are trying to find out the best way of giving stem cells to patients, where the cells go in the body, and how long they survive in the patient. We expect that, in the future, many more stem cell therapies will become available.
What are the different types of stem cells?
Embryonic stem cells, in the middle of the figure, can become three other types of stem cells: ectodermal, endodermal, or mesodermal stem cells. Ectodermal stem cells become skin cells and neurons (brain cells), and endodermal stem cells become lung cells, thyroid cells and cells of the pancreas.

How long after conception do embryonic stem cells grow?
1. The embryonic stem cells are harvested 5-7 days after conception.#N#Adult stem cells do not provide the same benefits as embryonic ones from a therapeutic standpoint. They fall short in their viability to treat genetic diseases. That’s because the same disease found in the adult body can be present in their stem cells. When the harvesting takes place, it occurs during the first week after conception. At this stage, the embryo has not yet developed to a stage where a personal identity can be assigned to it, nor can it live outside of a specialized environment. It is essentially a mass of cells.
