What is the process used for harvesting embryonic stem cells?
you collect them from the amilical cord
A more ethical way to harvest stem cells? ... towardharvesting embryonic stem cells in a less controversial way. Together, these efforts represent a bid to break the stem-cell impasse in the lab ratherthan in the courts or the halls of ... (Stem-cell researchers say it's too early to know if adult stem cells
Both adult and embryonic stem cells can cure diseases that are considered malignant. However, adult stem cells are more recommended than the latter because of its legal procedures in harvesting (no need of killing an embryo). These type of stem cells can be found in bone marrow, mammary gland, blood, umbilical cord, lining of the nose and human testicles.
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.
Stem cells are cells that have not specialised. Specialist cells can only be the one thing that they are specialised for; ie, you cannot turn skin cells into a heart, or liver cells into a brain. Stem cells have not specialised and can therefore become any type of cell. I am not sure how they are stimulated to become one kind or another, but they can. Adult stem cells are not as good as embryonic…
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.
Somatic stem cells are more differentiated than embryonic stem cells, that is, they become specialized for a particular lineage of cells. The types of cells that can originate from a somatic stem cell is limited whereas embryonic stem cells, being less differentiated, are capable of giving rise to almost every cell type.
