Embryos have a higher percentage of stem cells than adults because they are in a rapid stage of development, requiring a greater number of undifferentiated cells that can differentiate into various cell types. These pluripotent stem cells enable the formation of all tissues and organs during the early stages of growth. As organisms mature, stem cells become more specialized and their numbers decrease, leading to a higher proportion of differentiated cells in adults. This transition is essential for the proper functioning and maintenance of adult tissues.

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?
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.
What will happen if the percentage of red blood cells is higher or lower from the normal value?
the baby will die!
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.
Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
Which cells are removed from early embryos?
Stem cells.

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.

What has a higher percentage blood or water in the body?
Water As blood is made from water and blood 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.
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.
Do embryos contain totipotent cells?
Yes, embryos contain totipotent cells, which are the earliest cells formed after fertilization. These cells have the ability to develop into any cell type in the body, as well as the extraembryonic tissues, such as the placenta. Totipotency is typically present in the first few cell divisions of the zygote, after which cells begin to differentiate into pluripotent cells, which can still form many, but not all, cell types.
What is the difference between embryonic and adult stem cells?
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
