Explain that these new, slightly specialised cells are also stem cells because they are able to produce a range of specialised cells, but they are each only able to produce a particular range of types. These slightly specialised cells also divide to produce more identical cells, or cells that develop into even more specialised cells. Continue the diagram for another level or two. Ideally, use a graduation in tint for each ‘cell line’.
