Tissue Image Gallery

Visual analysis of animal and human tissues is critical to understand complex diseases such as cancer or neurodegeneration. From basic immunohistochemistry to intravital imaging, confocal microscopy…

Virally labeled neurons (red) and astrocytes (green) in a cortical spheroid derived from human induced pluripotent stem cells. THUNDER Model Organism Imagerwith a 2x 0.15 NA objective at 3.4x zoomwas used to produce this 425 μm Z-stack (26 positions), which is presented here as an Extended Depth of Field(EDoF)projection.

Neuroscience Images

Neuroscience commonly uses microscopy to study the nervous system’s function and understand neurodegenerative diseases.

Multicolor Image Gallery

Fluorescence multicolor microscopy, which is one aspect of multiplex imaging, allows for the observation and analysis of multiple elements within the same sample – each tagged with a different…

Cell Biology Image Gallery

Cell biology studies the structure, function and behavior of cells, including cell metabolism, cell cycle, and cell signaling. Fluorescence microscopes are an integral part of a cell biologist…

Kinetochore Assembly during Mitosis with TauSTED on 3D

Three-dimensional organization of the mitotic spindle together with the distribution of CENP-C and BUB1 based on TauSTED with multiple STED lines (592, 660 and 775 nm) can provide insights…

How to Quantify Changes in the Metabolic Status of Single Cells

Metabolic imaging based on fluorescence lifetime provides insights into the metabolic dynamics of cells, but its use has been limited as expertise in advanced microscopy techniques was needed. Now,…

Regulators of Actin Cytoskeletal Regulation and Cell Migration in Human NK Cells
