U17-E01. Leica TCS-SP5 confocal microscope

Leica TCS-SP5 confocal microscope with especial features that allows studying interactions between cells/tissues and materials. Indeed, the experience of the research group in charge of this Unit makes this a unique service for the study of cells and tissues and the interactions between various materials and cell components as well as between implants/scaffolds and tissues of the recipient organism. For example, it makes it possible to characterize in detail the specific markers of particular cell populations for tissue engineering applications and in vitro tests of biocompatibility of new materials, allowing the process of cell colonization of surfaces to be explored and simultaneous analysis of the cells or subcellular structures and materials. The combined use of fluorescence and reflection makes it possible to study the tissue-implant interface, with up to 8 fluorophores, at wavelengths from 405 to 633 nm allowing histological studies of a wide range of tissue types which would be restricted at certain fixed wavelengths due to autofluorescence phenomena.

Confocal Microscopy Service

The Confocal Microscopy Service offers the possibility of making optical section of samples and enabling their three-dimensional reconstruction, which allows their visualization in high resolution with exceptional clarity and detail.
The unit is equipped with a Leica TCS-SP5 confocal microscope. The confocal module is equipped with three spectral detection channels, AOBS (Acousto-optical beam splitter) and a resonant scanner system that allows analysis at high speed and resolution and makes possible the analysis of dynamic in vivo physiological processes in short periods of time, significantly improving the survival of living biological samples by shortening the exposure times to lasers. Includes 1 argon laser, 1 He/Ne laser, 1 DPSS laser diode and 1 violet excitation laser. The microscope is coupled to a cell incubation kit that allows multi-position time lapse experiments. The equipment includes a workstation and four software for acquisition and analysis, which allow 3D visualizations, co-location studies, FRAP (Fluorescent Recovery after Photo-bleaching), FLIP (Fluorescent Loss in Photobleaching) and FRET (Fluorescence Resonant Energy Transfer). The equipment allows 3D characterization in detail of living cells and tissues through the use of different fluorochromes, expression and localization of molecules in 2/3D, colocalization and interaction of proteins or other types of molecules; endocytosis and intracellular transport, in situ hybridization with fluorescent probes, interaction studies between cells and materials, etc.
The unit provides researchers with a wide array of routine and specialized services as well as the latest advances in microscopy, including technical and scientific support to scientists for the study of cell/tissue biology, physiology and pathogenesis of diseases. Overall, the Confocal Microscopy Service serves as a valuable tool to advance scientific research and understand complex biological systems at the cellular and molecular level.
