Stem cell research. Researcher studying stem cell nuclei (white on screen) under a light microscope. The nuclei contain the cells' genetic information in the form of deoxyribonucleic acid (DNA). Stem cells are pluripotent, they are able to differentiate into any of the cell types of the body. Stem cell differentiation can be initiated in the laboratory by the use of biochemical growth factors. Stem cells are a potential source of cells to repair damaged tissue in diseases such as Parkinson's and insulin-dependent diabetes.
