In a human embryo, up to the

, all the cells are

and could produce any sort of cell required by the organism.
They are called

After this point the cells become

Although body cells in an organism contain the

, many genes in a particular cell are

This is because it only produces the specific

In carefully controlled conditions of mammalian

inactive genes in the nucleus of a body cell to form cells of all tissue types.
Adult and embryonic stem cells have the potential to produce cells needed to replace
