you collect them from the amilical cord
The major issue involving the harvesting of embryonic stem cells is that the embryonic stem cells can cause the destruction of an embryo.
the process used in harvesting adult stem cells
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
adult stem cells are harvested from bone marrow.
adult stem cells are more rare, where embryonic stem cells are a lot easier to be found. but embryonic stem cells are more likley to be rejected if they are used for transplants.
They are not better, embryonic stem cells can become more types then adult.
embryonic stem cells can differentiate into more types of cells
similarties of an adult and embryonic stem cells?
adult body cells have a function where as embryonic stem cells have no set function as of that stage. now there are some adult stem cells and those have little to no difference than embryonic 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.
Embryonic stem cells can differentiate into more types of cells
Adult stem cells are more specalized than their embryonic counterparts, embryonic stem cells can become any cell whereas adult stem cells can only be used to form certain 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 stem cells, but because harvesting embryonic stem cells requires the destruction of a human embryo it is banned in many countries.
embryonic stem cellsadult or somatic stem cells
The main controversy is whewn stem cells are harvested from aborted fetuses, or when an egg is fertilized in a laboratory for the sole purpose of harvesting stem cells. Stem cells can also be gotten from umbilical cord blood after a baby is born.
Embryonic stem cells are used to treat a variety of diseases. Stem cells also help organs and tissues repair themselves.
Sacrifice a embryo at the blastocoel stage. Obtain the stem cells from the blastomere.
Using embryonic stem cells for research is not murder.
There are two types of stem cells: Embryonic Stem Cells and Adult Stem Cells.Embryonic stem cells are isolated from:The blastocystAdult Stem Cells are isolated from: Bone MarrowFats or Lipids (Known as Adipose Tissue)Blood
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.
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.
embryonic stem cells are special because they can generate all cell types in the body!
Researchers use embryonic stem cells to study diseases such as Parkinson's. They can be used to develop cures.
There are two types of stem cells adult, which are taken from a person once they are born, and embryonic, which are taken from embryos still in the mothers womb.
