A stem cell is an undifferentiated cell, which retains the ability both to keep dividing for self-renewal of its population, and to become specialized in certain conditions. Embryonic stem cells occur in the early embryo, and have the ability to differentiate into any of the 200-plus types of specialized cells in the eventual body. Adult stem cells occur in certain tissues where they multiply rapidly as part of ongoing maintenance. In the bone marrow they produce millions of different blood cells every second.
In mature animals, Cell division is mainly of differentiated cells for repair and replacement. In plants, many cells can differentiate into any type of cell throughout their life.
What are the different types of stem cells?
Embryo stem cells can be treated with particular proteins to turn genes on and off they can also differentiate into different tissues which allow them to repair damaged body parts.
Bone marrow stem cells can develop into red or white blood cells or into cells to repair bones, cartilage, tendons or fat tissues.
What are adult stem cells?
An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ that can renew itself and can differentiate to yield some or all of the major specialized cell types of the tissue or organ. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found.
Where are adult stem cells found?
