Where do scientists get embryonic stem cells?
Embryonic stem cells are typically obtained from excess embryos created during in vitro fertilization procedures with informed consent from the donors. These embryos are usually donated for research purposes and are not created for the sole purpose of harvesting stem cells.
Controversy of stem cells?
Stem cell research and therapy have sparked controversy due to ethical concerns related to the use of embryonic stem cells obtained from human embryos. This has raised ethical debates around the beginning of life and the destruction of embryos. Some oppose this research on moral or religious grounds, while others argue for the potential benefits of stem cell therapies in treating various diseases and injuries.
Do scientists need embryos to further the stem cell research?
Cloning is asexual reproduction. There are all kinds of research that can be done on stem cells without creating any actual embryo or causing the gestation of an embryo in order to give birth to a new organism.
What are three sources of stem cells?
Embryonic stem cells can be obtained from early-stage embryos. Adult stem cells are found in various tissues throughout the body, such as the bone marrow or brain. Induced pluripotent stem cells are created by reprogramming adult cells, like skin cells, to develop stem cell properties.
Are people more upset about some types of stem cells than others?
Yes, embryonic stem cells tend to elicit more controversy and raise ethical concerns compared to adult stem cells. This is because obtaining embryonic stem cells usually involves the destruction of human embryos, which some people view as morally objectionable. Adult stem cells, on the other hand, are obtained without harming embryos and are therefore generally accepted with fewer ethical objections.

How can one obtain embryonic stem (ES) cells for research purposes?
Embryonic stem (ES) cells can be obtained from embryos that are donated for research purposes. These embryos are typically leftover from in vitro fertilization procedures and are donated with informed consent. Researchers can then extract the ES cells from these embryos for use in research studies.
How do you obtain embryonic stem cells for research purposes?
Embryonic stem cells are typically obtained from unused embryos created during in vitro fertilization procedures. These embryos are donated for research with informed consent from the donors. The stem cells are then isolated from the inner cell mass of the embryo for further study and experimentation.

Which cells are removed from early embryos?
Stem cells.

Are stem cells human?
Yes, some stem cells do come from humans. The stem cells are taken from embryos. Animals also have stem cells used in research.

What sources of stem cells presents the greatest ethical problems or controversies?
Embryonic stem cells present the greatest ethical problems as they are obtained from embryos, which leads to debates about the moral status of the embryo and concerns about potential destruction of human life. Additionally, induced pluripotent stem cells, which are created by reprogramming adult cells, also raise ethical considerations due to issues related to genetic manipulation and informed consent.
How old does a zygote have to be to get stem cells?
Stem cells are typically obtained from embryos that are a few days old, known as blastocysts. At this stage, the embryo has developed into a hollow ball of cells with an inner cell mass that contains embryonic stem cells. These cells can be extracted and grown in laboratories for research and potential therapeutic purposes.
What is the main source of embryonic stem cells?
The main source of embryonic stem cells is embryos that are created in a laboratory through in vitro fertilization techniques. These embryos are usually donated for research purposes with informed consent from the donors. Embryonic stem cells are pluripotent, meaning they have the ability to differentiate into all cell types in the body.
