Human embryonic stem cell (gold) growing on a layer of supporting cells (fibroblasts). Stem cells are derived from very early embryos and can either be grown to stay in their original state or triggered to form almost any type of human cell. The fibroblasts provide special factors that maintain the stem cells in their original state. The stem cell appears to be grasped by the underlying fibroblast. Stem cell research could lead to cures for many diseases such as Parkinson's disease, Alzheimer's and diabetes, where a patient's cells are damaged or absent.

Goblet cells are packed full of mucous globules (blue), which they release to provide lubrication and protection to the inner surfaces of the intestine and the respiratory system among others. The mucous globules are condensed inside the goblet cell but expand hugely once they are released, absorbing water within 20 milliseconds. This rapid release occurs in response to lots of different stimuli and allows the mucous to get to work instantly.

Aspirin crystals. Aspirin was originally extracted from willow bark but is actually produced in all plants as a defence mechanism in response to damage or attack. Much higher levels are therefore found in less than perfect fruit and vegetables. Aspirin is used to treat pain, reduce fever and to prevent heart disease and cancer. Some people think it should be reclassified as a vitamin.
