What are the differences between embryo and adult stem cells?
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.
Where at in the human body are stem cells?
There are adult stem cells and there are embryonic stem cells. Adult stem cells are found in many body tissues such as in the brain, neural stem cells, and in bone marrow. Also the embryonic stem cells, as you can tell by the name, are from the embryo which starts to develop into more recognizable specialized stem cells within three to four weeks after fertilization.
Are Adult stem cells as useful as Embrionic stem cells?
Yes and No. The only big difference is the procedures used in harvesting adult stem cells is considered legal and safe. There's no need to kill a human embryo. Adult stem cells can be harvested from cord blood or human bone marrow. But embryonic stem cells are able to make more kinds of cells than adult stem cells.
Why might an adult human have more cells then a baby human?
The adult is bigger so it needs more cells than a baby.
How are adult stem cells better then embryonic stem cells?
They are not better, embryonic stem cells can become more types then adult.
Which parts of the human body contain stem cells?
There are two kinds of stem cells: Embryonic and adult. 1. Embryonic stem cells are found in embryos. An embryo develops from a fertilized egg, or zygote, and after about 4-5 days it reaches the stage where 50-150 cells are colonized. This means that one fertilized egg divides into 50-150 cells, which are considered embryonic stem cells. Also, they are totipotent, meaning that they can reproduce indefinitely, and can give rise to any type of cell. 2. Adult stem cells, or somatic stem cells, can be found in adult tissues throughout the human body. As adult stem cells are tissue specific, they are in the already developed tissues. Some examples of where you can find stem cells in the human body: Bone marrow= hematopoietic (blood) stem cells which differentiate into blood cells endothelial stem cells = diff. into blood vessels (arteries, veins) mesenchymal stem cells = diff. into bone, cartilage, muscle, fat, fibres Cord blood= blood stem cells (similarly to bone marrow) (Because of this similarity they might be considered as an alternative for bone marrow transplant.) fat = adipose stem cells, also similar to bone marrow, as they can differentiate into bone, cartilage, fat, and muscle. Stem cells exist also in human skin, mammary glands, placenta, lungs, and the brain (in which neural stem cells may or may not exist; it is up for debate). The main function of adult stem cells is to replace damaged, or dying cells. They are pluripotent. Therefore, they too can reproduce indefinitely. However, while embryonic stem cells are able to develop into any kind of cell, adult stem cells are more limited. Umbilical cord blood considered to contain "adult" stem cells, since they are not part of the embryo anymore. The use of embryonic stem cells for research purposes is a highly debated question. However, research done on using adult stem cells is more widely accepted. Adult stem cells, found in bone marrow and in umbilical cord blood, are used routinely today. Fortunately, pluripotent (adult stem cells) can be "reprogrammed", and, as a result, they could be regarded as equivalent to embryonic stem cells. Just for an interest: deciduous baby teeth (milk teeth, which babies shed) can also be used as a source for adult stem cells. Stem cells, with the ability to develop into different cell types, can be found not only in humans, but also in plants and animals.
Why muscle cell found in heart contain many more mitochondria than cells that store fat in adult humans?
Heart is very active than fat storing cells. It needs more energy
How many unipotent stem-cells are in An adult?
more than 200 cells
Where do you find blood stem cells?
Blood stem cells can either be found in a baby's umbilical cord or in a qualified donor's bone marrow. It might also be found in human embryo but the procedure in harvesting it is considered unethical. For more successful life stories about cord blood transplant, search it online.
What makes embryoic stem cells useful for medicine?
They can differentiate into more cells than adult stem cells can.
What makes embryonic stem cells useful for medecine?
they can differentiate into more cells than adult stem cells can.
Why do adult stem cells currently have fewer uses in therapeutic cloning that embryonic stem 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.
