What do scientists do to adult cells to make them behave like embryos?
What do scientists do to adult cells to make them behave like embryos?
Which type of stem cell is less controversal?
Adult stem cells are much less controversial. This is because they do not involve embryos at all. However, adult stem cells cannot differentiate into as many different types of cells as the embryonic stem cell (which can become any type).
What are the main animal sources of stem cells?
The main animal sources of stem cells include embryos, which provide embryonic stem cells known for their pluripotency, meaning they can differentiate into any cell type. Adult animals also contain stem cells, primarily in tissues like bone marrow, fat, and muscle, which are referred to as adult or somatic stem cells and typically have more limited differentiation potential. Additionally, induced pluripotent stem cells (iPSCs) can be generated from adult somatic cells by reprogramming them to a pluripotent state, enabling them to behave like embryonic stem cells.
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.
What are two sources of stem cells?
Embryonic stem cells are derived from embryos and have the potential to develop into any type of cell in the body. Adult stem cells are found in various tissues and can give rise to specific types of cells in that tissue.

What are the types of stem cells?
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
What is the debate about stem cells?
Scientists believe stem cells from human embryos could hold the key to treatments and cures for disease. Basically it is a debate about stem cell research.
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.
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.
Should frozen embryos created through in vitro fertilization be used to create stem cells?
Most scientists agree that frozen embryos created through in vitro fertilization should be used to create stem cells, although many people are against it because of their religious views.
What are other sources of stem cells besides human embryos?
Besides human embryos, stem cells can be sourced from adult tissues, such as bone marrow and adipose (fat) tissue, where they are known as adult or somatic stem cells. Additionally, induced pluripotent stem cells (iPSCs) can be created by reprogramming adult cells, such as skin or blood cells, to an embryonic-like state. Other sources include umbilical cord blood and placental tissues, both of which contain hematopoietic stem cells. These alternative sources provide valuable options for research and therapeutic applications without the ethical concerns associated with embryonic stem cells.
Which cells are removed from early embryos?
Stem cells.
