What organs use stem cells?
Scientists are discovering that many tissues and organs contain a small number of adult stem cells that help maintain them. Adult stem cells have been found in the brain, bone marrow, blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, and other (although not all) organs and tissues.
Can stem cells repair organs?
Embryonic stem cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
What are 2 treatments from stem cells?
The best-defined and most extensively used stem cell treatment is hematopoietic (or blood) stem cell transplantation, for example, bone marrow transplantation, to treat certain blood and immune system disorders or to rebuild the blood system after treatments for some kinds of cancer.
What are the 2 major types of stem cells?
Types of stem cells
- Embryonic stem cells. Embryonic stem cells come from human embryos that are three to five days old.
- Non-embryonic (adult) stem cells.
- Induced pluripotent stem cells (iPSCs)
- Cord blood stem cells and amniotic fluid stem cells.
Can a stem cell be used to make an organ?
The biggest challenge right now is that we can push a stem cell to a single cell fate or specialized cell state, but in a tissue there’s multiple cells. An organ like your heart or your brain, it’s not just made of one cell type. It’s made of many cell types working together.
How are stem cells being used to repair the heart?
At USC, two stem cell researchers are tackling heart repair from other directions. In the lab of Henry Sucov, researchers aim to harness the heart’s innate ability to heal. They’re studying a regenerative type of heart muscle cell called a mononuclear diploid cardiomyocyte.
Are there any stem cells for human kidneys?
So far, scientists haven’t been able to create complete adult human kidneys—they’re too complex. At USC, though, McMahon’s lab is coaxing stem cells to organize themselves into simplified, mini versions of this elaborate organ.
Are there any stem cells in the adult body?
Newborns have large numbers of these cells, but adults have relatively few, so the adult body has trouble regenerating heart tissue after injury. When they looked for these cells in mice, they found that some mice had more of these cells than other mice did.
