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.
And embryonic stem cell is taken from an embryo at a very early stage of its development. The embryo is so small at that point that taking the stem cells destroys the embryo. An adult stem cell is taken from an adult and doing so does not destroy the adult. Adult stem cells are thought to be less flexible than embryonic stem cells and therefore less suitable for certain processes.
The adults have more freedom and can make decisions for themselves. They usually try to have a job or other productive role in society. The embryonic cells are the opposite, being very dependent on the mother for everything.
There are two types of stem cells adult, which are taken from a person once they are born, and embryonic, which are taken from embryos still in the mothers womb.
adult stem cells are more rare, where embryonic stem cells are a lot easier to be found. but embryonic stem cells are more likley to be rejected if they are used for transplants.
An embryonic stem cell is young, undifferentiated, pluripotent, and unspecialized, so it can turn into any body cell. This makes it the most versatile option. Adult stems can change identity, but are not as versatile for research.
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
Yes and No. The only big difference is the procedures used in harvesting adult stem cells is considered legal and safe. There's no need to kill a human embryo. Adult stem cells can be harvested from cord blood or human bone marrow. But embryonic stem cells are able to make more kinds of cells than 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.
the embryo is killed
There are more cells found in an embryo than an adult.
.......... Did Ben ask this??????
Embryo, between the 3rd and 8th week. Fetus, after the 8th week

The main similarity between embryonic and adult stem cells is their ability for self-renewal.
This cluster of cells change the baby grows from pre-embryo to embryo to fetus.

Specialization.
What kind of cleavage are you referring to? Cleavage could refer to a cleavage furrow during cytokinesis or to the splitting of cells in an embryo or to any other sort of separation. Please specify.
