STEM CELLS

Undifferentiated cells are called stem cells and can divide to produce more undifferentiated cells. They can differentiate into different types of cell, depending on what instructions they're given.

1) Stem cells are found in eary human embryos. They have the potential to turn into any kind of cell

2) Adults also have stem cells, but they're only found in certain places, like the bone marrow

3) Unlike embryonic stem cells, adult stem cells can't turn into any cell type- only certain ones

4) You can clone stem cells from embryos and the bone marrow and made to differentiate into specialised cells to use in medicine or research
