Striking images reveal new insights into how the kidney develops from a group of cells into a complex organ.
This picture shows two nephrons growing in the laboratory. The green and red areas highlight cells that filter waste products from the blood. The blue section shows where urine is collected and taken away for excretion. Scientists have found that a molecule called beta-catenin instructs kidney cells to form these distinct areas of the nephron.
