Embryonic stem cells come from umbilical cords in small quantities, which are harvested by collecting cord blood.
Cord blood stem cells come from a newborn's umbilical cord while embryonic stem cells are harvested from a human embryo. Although the procedures involved in harvesting it are totally different. A doctor can immediately removed a newborn's umbilical cord and squeeze out those stem cells. Getting stem cells from the embryo requires to kill a forming fetus inside the womb and this procedure is considered unacceptable.
If you would like to learn some more facts about umbilical cords a great place to check is the Brewer Diet. I highly recommend it as it has come in handy many times.
Stem cells are the undifferentiated cells that have the ability to renew themselves for several generations. These cells are located on the matured or maturing organ systems of the adult or children. Found in Large Number of tissues, including epithelial layers of our skin. Umbilbical cord Embryo
the chickens that i have dont. When a chick grows in an egg it does have an umbilical cord connecting it to the yolk to give it nourishment while it grows. Once the chick hatches it will come off in a day or two. I am not sure if the umbilical cord is there even if an egg isn't fertilized but I would guess that is what those white stringy things in our eggs are?
Comes from the brain cords, they help your brain cells in order to live
i don't think so but if they do it is very tiny tinny!
No. The young of all birds including geese come from eggs which are laid by the mother, so the baby is in the egg outside the mother for some days before the egg is hatched.

Yes. Embryonic stem cells are controversial due to the destruction needed of a fetus. The debate over this is whether the unborn child has a right to life. (Embyonic stem cell debate). However, there are adult stem cells that come from adults. Scientists have been able to get these adult stem to replicate embryonic stem cell properties, and depending on who you ask, the adult stem cells have proven more useful than embryonic stem cells. Since adult stem cells do not destroy anybody, there is nearly non-existant debate with this.
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.
These two transplants are similar because they use stem cells as their way to cure a person's malignant disease. The only big difference is stem cells used in cord blood transplant come from a newborn's umbilical cord. This cord is commonly referred to as cord blood and it is similarly effective as the stem cells found in bone marrow. One cord blood might not be enough to cure an adult. An adult needs two units of cord blood to get cured.
A transient group of cells that come together temporarily and then disperse is called a transient structure or a cell cluster. These cell clusters can form during processes like embryonic development, wound healing, or immune responses.
