Protéines d'adhésion dans une cellule souche en microscopie de fluorescence confocale

Adhesion proteins in a stem cell, observed using a Zeiss LSM 700 fluorescence confocal microscope. In confocal microscopy, the sample is scanned by laser beams, point by point. This technique produces fine optical sections (at different levels in a thick sample) that reveal the location of numerous entities or cell types in a section of tissue or individual cells. These optical sections are then stacked to generate 3D images of samples. This technique, used commonly in laboratories, is improving all the time in terms of the resolution, sensitivity, colours and contrasts possible.
