Image Gallery: Tunable Multicolor Deep In Vivo Imaging

With the SP8 DIVE Multiphoton Microscope

Today’s life science research focusses on complex biological processes, such as the causes of cancer and other human diseases. A deep look into tissues and living specimens is vital to understanding the conditions and mechanisms in cells and finding answers to crucial questions challenging the life sciences.

The SP8 DIVE Deep In Vivo Explorer is a multiphoton microscope with spectrally tunable non-descanned detection that provides unlimited flexibility, so that users can optimally distinguish components and structures deep in tissues and living organisms. The SP8 DIVE comes with the unique 4Tune detection that offers full spectral freedom and allows the detection of multiple transgenic markers with perfect color separation in a single experiment.

See the image gallery with examples from a range of applications that the SP8 DIVE can be used for.

Deep in vivo multicolor imaging

Small intestines of a confetti mouse, fluorescently labeled and lineage traced from a multi-color tracer. The gray color codes for the SHG signal from collagen. Lineage traced stem cells are shown in cyan (CFP), green (GFP), yellow (YFP), and red (RFP). Image size is approximately 700x700x150 μm³. Recorded with two-photon excitation using the SP8 DIVE.

Transgenic and transiently labeled mouse brain. Different types of nerve cells are shown in green (microglia, GFP), yellow (neurons, YFP), and blue (astrocytes, sulforhodamine), while the blood system is shown in red (Alexa680-dextran).

Label-free imaging: Second (SHG) and third harmonic generation (THG)

The small intestine of Lgr5CreERT2-GFP confetti mice. Gray: SHG signal (collagen 1) which is used as an orientation landmark. Green: Lgr5+ stem cells. Red, cyan, and yellow, traced cells that are progeny of the Lgr5 stem cells. Sample courtesy of Prof. Jacco van Rheenen, Netherlands Cancer Institute, Amsterdam (the Netherlands).

Mouse brain cortex. Thy1-eYFP cortical neurons, THG blood cells. Excitation: 1300 nm. Objective: IRAPO 25x1.0 W motCorr. 70 fps, 256x256 px. Sample courtesy of Kevin Keppler, Light Microscopy Center, DZNE, Bonn, Germany.
