  Hi. There are cells that can make different types of organs in many parts of the body. For example, there are cells you can get out of muscles that can make bone! When they are in muscle, they are muscle. When they are not, they can be other things. This can be done by changing the environment they are in such as growing them on something stretchy for muscles or something stiff for bones. Treating with different hormones can also help.
