| pubmed-article:15368965 | pubmed:abstractText | Confocal microscopy offers important advantages compared to conventional epifluorescence microscopy. It works as an "optical microtome" leading to a accurate image resolution of a defined focal plane. Furthermore, the addition of a Nipkow disk on the confocal microscope greatly accelerates the image acquisition, up to 30 frames per second. Nevertheless, the software-assisted mathematical restoration of images acquired using a wide-field microscope allows to get images with a resolution similar to the one obtained in confocal microscopy. These imaging technologies allowed us to monitor on line cardiac differentiation of murine embryonic stem (ES) cells within 3D structures called embryoid bodies. The high rate acquisition of images using the confocal microscope equipped with a Nipkow disk allows to monitor calcium spiking in differentiating cardiomyocytes within embryoid bodies. | lld:pubmed |
