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.
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.
This type of research requires that cells are taken from an embryo. Some people are opposed to stem cell research because they think it is unethical.
Hypocotyl is the part of the embryo that becomes the lower part of the stem and the roots. Epicotyl is the part of the embryo that becomes the upper part of the stem.

I think it's when a stem cell from an embryo is taken and has repaired a tissue. (I think) Anyone else know?

Stem cells are pluripotent, that is, they have the ability to differentiate and become any cell type in the body.

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.
