- There are two main types of stem cells: Adult stem cells and Embryonic stem cells
- In bodily tissues like bone marrow and muscle tissue,adult stem cells generate replacements for bone and muscle cells that are lost through injury, disease or normal wear or tear.
- Adult Stem cells usually develop into the same type of cell as the tissue they reside in. An adult stem cell forming in muscle tissue.For example,normally gives rise to muscle cells.
- Embryonic stem cells, however, are like "Starter cells" that can be coaxed into becoming a variety of other types of cells.
- By turning into bone cells, nerve cells and other types of cells, embryonic stem cells develop into the specialized cells that create bone,nerve and other tissues in the human body.
