Morphology Project Summary/Abstract The Morphology Module has three primary functions. First, the module provides technical assistance for light, electron, and confocal microscopy. Services include paraffin, methacrylate, epoxy, epon, and frozen sectioning; and complete transmission electron microscopy and scanning electron microscopy services. Second, the module is an equipment resource, housing a laser microdissection system, two confocal microscopes including a new inverted confocal system, automated histology and electron microscopy tissue processors, ultramicrotomes, cryostats, various fluorescence and phase microscopes, computers and printers to process digital images. Third, the module provides consultation for various histology, electron microscopy and microscopy procedures and troubleshooting, and training on all microscopes.
