About this image

Confocal light micrograph of a collection of spherical colonies of stem cells. Each colony has been stained with a variety of fluorescent markers that highlight different structures within the cells when illuminated by a laser beam. Stem cells are the precursors to all the different types of cells in the body. They are being studied in the hope of finding treatments for many degenerative diseases. This image was captured digitally using a Leica DMIRB microscope. Department of Biochemistry, Hamilton, Ontario, Canada
