We need options :) but stem cells are a amazing type of cells that are able to develop into many different types of cells <span>First, they are unspecialized cells capable of renewing themselves through </span>cell division<span>, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.</span>

Oral ingestion or swallowing is the
administration method that takes the longest time for the drug to reach the
brain. When using this method, the drug is swallowed through the mouth, moves to
the stomach and then into the bloodstream before it can be transported to the
brain. This means that it takes longer for a swallowed drug to start functioning
than it does with other methods of administration such as injecting.
