In fat cells.
Stem cells are important cells found in all multi-celled organisms, that can divide and recognise problems. In mammals, there are two types of stem cells: embryonic cells, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, renewing and restoring adult tissues.
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.
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.
Adult stem cells
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.
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.

Yes. Embryonic stem cells are controversial due to the destruction needed of a fetus. The debate over this is whether the unborn child has a right to life. (Embyonic stem cell debate). However, there are adult stem cells that come from adults. Scientists have been able to get these adult stem to replicate embryonic stem cell properties, and depending on who you ask, the adult stem cells have proven more useful than embryonic stem cells. Since adult stem cells do not destroy anybody, there is nearly non-existant debate with this.
You actually can use the stem cells from adult bone marrow in stem cell research. The practice has been gaining momentum with discoveries relating to mesenchymal stem cells.
