Cell theory

All living things consist of cells, and every cell comes from another cell.

Matthias Schleiden (plants, 1838) and Theodor Schwann (animals, 1839) concluded that cells are the basic unit of life; Rudolf Virchow added in 1855 that new cells only arise from existing ones. Disease could now be understood as something that goes wrong inside cells. Cancer biology, stem cells and genetics all build on it.
