This site, supported by the National Institute of General Medical Sciences (NIGMS), the U.S. National Institutes of Health, and the American Society for Cell Biology, is a resource database of cell images, videos, and animations for use in research, education, and training. The historic and modern images are meant to show "cell architecture, intracellular functionalities, and both normal and abnormal processes" and can be searched by cell process, cell component, cell type, and organism. The Cell Library is also available as an app for iPhone and iPad.
