Stem cells are pluripotent, that is, they have the ability to differentiate and become any cell type in the body.
Stem cells come from newly fertilized eggs.
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.
the embryo is killed
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.
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.

Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.

There are more cells found in an embryo than an adult.
you do!
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.

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.
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.
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.
The cells are known as stem cells meaning they can become any cell type. The embryo becomes bigger because certain genes in the DNA are activated allowing the cell to divide or produce certain determination factors that will make a stem cell become a neuron, muscle cell, etc.... The embryo grows in size as the stem cells divide repeatedly and then some of the stem cells become actual specific cells.
