What part of a developing embryo are stem cells derived from?
Stem cells come from newly fertilized eggs.
What happens to the embryo once stem cells are removed?
Once stem cells are removed from the embryo, the remaining embryo cannot develop into a fetus because the stem cells are essential for its growth and differentiation. The embryo is typically discarded after the stem cell extraction process.
What happens to an embryo when stem cells are harvested from it?
the embryo is killed
Stem cells may be similar to the cells of a developing embryo because both cell types can?
Differentiate into various specialized cell types and have the ability to self-renew. This allows stem cells and embryonic cells to develop into different tissues and organs during growth and repair processes.
How Many Totiptent stem cells does a 5 week old embryo contain?
At around 5 weeks of embryonic development, a human embryo contains a relatively small number of totipotent stem cells, which are capable of developing into any cell type in the body, including the placenta. Initially, after fertilization, the zygote is totipotent, but as the embryo develops and cells begin to differentiate, this totipotent capacity diminishes. By the 5-week mark, the embryo has transitioned primarily to pluripotent stem cells, which can give rise to various cell types but not to the placenta. The exact number of totipotent cells at this stage is not well-defined, as most of the totipotent cells would have already given rise to pluripotent cells.

Where do neurons originate in the human body?
Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.

Are more stem cells found in an embryo or an adult?
There are more cells found in an embryo than an adult.
Who has the authority to decide if stem cells of an embryo are used?
you do!
How is stem cells different from adult animal cells?
A stem cell is a cell that has the ability to generate itself into any body part or cell type of the organism it is developing. Stem cells are found in the blastocyst of an embryo and ALSO in adults. Because adults have already finished developing, the stems cells are then used to maintain regenerative organs such as skin, blood or intestinal tissues. All other adult cells do not have the ability to regenerate.

Differentiate into various specialized cell types and have the ability to self-renew. This allows stem cells and embryonic cells to develop into different tissues and organs during growth and repair processes.
What embryonic stem cell mean?
Cells obtained from an embryo in the blastula phase, when they are still only a few days old. Because they have only begun to differentiate, these cells have the capability of developing into any cell in the human body, a fact which makes them potentially important in medicine.

Explain how a stem cell develops into an embryo?
Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of the blastocyst, an early-stage embryo.In other words, they do not become embryos, they are part of an embryo.
What are the differences between embryo and adult stem cells?
Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.
