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.
The mesoderm layer of the stem cell provides instructions for building the heart. Mesoderm cells migrate to form the cardiac crescent, which eventually develops into the heart tube and further into the mature heart during embryonic development.
Embryo cell cloning, also known as therapeutic cloning, is a process where a cloned embryo is created for the purpose of harvesting stem cells. These stem cells can be used for medical research or potentially for treating diseases. This technique is different from reproductive cloning, which involves creating a clone of an organism.
A plummule is a term used to describe the embryonic shoot or bud of a plant that develops from the plumule of a seed. It is the part of the seedling embryo that will eventually give rise to the stem and leaves of the plant as it grows.

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.

Stem cell transplants can be either auto (patient's own stored cells) or allo (related or unrelated donor.) According to the National Marrow Donor Registry, currently 3500 unrelated donor transplants are performed each year in the U.S. Auto transplants are at least twice as common but I didn't find a number for them.
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.
