THE SCIENCE OF STEM CELLS
A fertilised embryo that nestles into Activating just the uterine wall holds mammoth four genes can amounts of potential. The cells revert specialised destined to become a foetus at that cells moment all look alike and number in the mere hundreds. Yet the organism that will arise from this small enclave will one day boast trillions of cells and be composed of a plethora of specialist cell types. How can the multitude of different cell types that make up our eyes, brain, lungs and skin come from such a small number of similar cells? The answer to this exponential increase in complexity and specialisation comes from stem cells.
