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.
Tissue is an ensemble of cells that make up the organs in the body. Stem cells are cells that can be transformed into any of the specialized cells that can be found in the tissues of the human body.
stem cells
Within the human body, stem cell niches maintain adult stem cells in a quiescent (inactive) state.
Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.
Stem cells are different from other cells in the body in several notable ways. They can divide and renew themselves many times, whereas other cells are more limited in their divisions. And when those stem cells divide, the new cells can become specialized if necessary. Stem cells have no assigned function in the body, but through the process of specialization, they can take on roles in any of the body's tissues. These type of cells can be derived from human embryos or from certain spots in the adult human body.
No. Stem cells occur naturally in the human body. However we are trying to clone stem cells to aid in there research.

When a human fetus is in its mother's womb, all of the cells that start to develop in it are stem cells. stem cells can form into any other type cell found in the human body. as the fetus continues to develop, the stem cells will change into whatever cells the baby needs(i.e., they will change into all the cells found in the human body)

Cord stem cells are exactly like normal stem cells, but they do come from an aborted fetus like most stem cells. Just like normal stem cells, they can be used to create any other cell needed in the human body.
They are called stem cells.

Human Stem Cells Institute was created in 2003.
Adult stem cells are undifferentiated cells, found throughout the body after development that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in juvenile as well as adult animals and human bodies. Creative Bioarray provides adult stem cells from various tissue/organs of human, mouse and rat.
