adult stem cells
The controversy surrounding stem cells arises out of the need to use stem cells from embryos which then get destroyed.
Embryos...
Witnesses do not believe in transplants of any kind, so they are against the use of stem cells.
A stem cell is a cell that has the ability to generate itself into any body part or cell type of the organism it is developing. Stem cells are found in the blastocyst of an embryo and ALSO in adults. Because adults have already finished developing, the stems cells are then used to maintain regenerative organs such as skin, blood or intestinal tissues. All other adult cells do not have the ability to regenerate.

Yes, some stem cells do come from humans. The stem cells are taken from embryos. Animals also have stem cells used in research.

Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
Stem cells can be harvested by destroying human embryos.
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
Scientists believe stem cells from human embryos could hold the key to treatments and cures for disease. Basically it is a debate about stem cell research.
