The image shows a 6 mm long, 12.5 day old mouse embryo obtained with the Mesolens. The inset shows a blow-up of the eye region revealing the individual cell nuclei. It is possible to identify fine structures throughout the embryo such as the developing heart muscle fibers and fine details in the eye such as the corneal endothelium using the Mesolens.
