How can a new body parts be made from stem cells?
Stem cells can be guided to develop into specific types of cells through a process called differentiation. By providing the right signals and environment, stem cells can multiply and mature into various cell types, allowing for the regeneration of new body parts. This process holds promise for organ replacement and tissue repair in regenerative medicine.
Why do scientists use embryonic stem cells instead of adult stem cells?
Scientists often use embryonic stem cells because they are pluripotent, meaning they can differentiate into any cell type in the body, which provides greater versatility for research and potential therapies. In contrast, adult stem cells are typically multipotent, limited to differentiating into a narrower range of cell types. Additionally, embryonic stem cells can be cultured indefinitely in the lab, allowing for more extensive study and experimentation. However, ethical considerations surrounding the use of embryonic stem cells have led to ongoing debates and research into alternatives.
Why do adult stem cells currently have fewer uses in therapeutic cloning that embryonic stem cells?
Adult stem cells have more limited differentiation potential compared to embryonic stem cells, making them less versatile for therapeutic cloning. Additionally, adult stem cells are often harder to manipulate in the lab and may not replicate as easily as embryonic stem cells. However, adult stem cells have the advantage of being less likely to be rejected by the recipient's immune system, which can be a benefit in certain therapeutic applications.
What are the easiest cells to grow in a lab?
epithelial cell
Why is using adult stem cells much less controversial?
Most likely because embryonic stem cell research is often associated with another controversial social issue-- abortion. Some (but not all) embryos used in stem cell research have been donated for research, but the donors are clinics which perform abortions. Also, even in cases that did not involve abortion, such as excess embryos from fertility clinics, some opponents of using embryos believe life begins when an egg has been fertilized, so therefore, the embryo represents human life, and to destroy any embryo to do stem cell research is thus immoral. Although not everyone agrees that a fertilized egg is the same as a human being, the pro-life community has been very vocal in opposition, keeping embryonic stem cell research mired in controversy. On the other hand, extracting adult stem cells does not require destroying an embryo nor does it affect a fertilized egg, so some pro-life supporters feel it is morally preferable to use adult stem cells for research. Unfortunately, adult stem cells are not as helpful to utilize in research because they cannot do some of the things that can be done with embryonic stem cells. Thus, this too is controversial, as scientists and researchers believe they are being hampered in finding cures for diseases because of the religious beliefs of certain people who oppose the use of embryonic stem cells.

Which type of cells are quite easy to grow in the lab?
Stem cells
How long do stem sells last within a human?
Theoretically, with the proper preservation in a lab, stem cells may last indefinitely. The first cell lines still exist. In the body, one produces undifferentiated cells in their marrow up until death.
Are red blood cells and white blood cells derived from the same original stem cell?
Blood stem cells like other stem cells can self-renew or copy themselves. They also produce different types of specialized cells found in the blood. Embryonic cells have the potential to make any cell type of the body. Researchers have made both red blood cells and white blood cells in the lab.

What advantages do embryonic cells have over adult stem cells in medical research?
Embryonic stem cells are useful in medical research because it is the most primary form of stem cells and thus it can be easily developed into almost endless types of cells.
Is the sodium made in a lab?
No sodium is not made in a lab
Why do some people feel that stem cell shouldn't be used?
Certain experiments in stem cell research requires embryonic stem cells that are obtained from developing embryos. Unfortunately, this is an invasive procedure that involves inserting a needle-like probe into the mother and extracting stem cells from the embryo. The procedure carries with it a high risk of damaging the embryo thus causing developmental abnormalities in the developing fetus. This raises ethical reasons. After much debate, interest groups have begun petitioning the ban on stem cell research.
How do scientists make artificial blood?
Scientists can make artificial blood by starting with either synthetic blood substitutes or lab-created red blood cells. They can use hemoglobin-based oxygen carriers or perfluorocarbons in synthetic blood substitutes, while lab-created red blood cells can be generated from stem cells in a culture dish. These artificial blood products are being developed as potential alternatives for blood transfusions in certain medical situations.
