Stem cell research. Tube of screened cells being held in front of a cell screening machine in a stem cell research laboratory. The machine sorts the cells by properties such as size, with graphs seen in the background. Stem cells are cells that differentiate to form the range of different tissues found in the human body. The type of cell they mature into depends upon the biochemical signals they receive. Stem cells are found in bone marrow, umbilical cord blood and embryos. Stem cells are being studied to find treatments for disorders of the blood and organs such as the heart, brain and kidneys. This work is being carried out at the Genethon facility in Evry, France.
