Physiology Image Gallery

Physiology is about the processes and functions within a living organism. Research in physiology focuses on the activities and functions of an organism’s organs, tissues, or cells, including the…

THUNDER image of a section of mouse lung where the mouse was inoculated with the Puerto Rico 8 strain of influenza virus. The lung tissue was immunofluorescently stained with Keratin-5 (green) and PDL-1 (red). Image courtesy of Andrew Beppu, Stripp Lab, Cedars Sinai Medical Center, Los Angeles, USA.

Monitoring Immunosuppressive Mechanisms from Infection

This application note discusses the importance of fast, sensitive, and haze-free imaging for the monitoring of immunosuppression in mouse lung epithelial tissue infected with the Puerto Rico 8…

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.

Pollen Flower - Taken with a 20x/0.8 objective, area of 6mm² with a depth of 100μm. 15 stitched tiles with 4 colors (DAPI/GFP/TRITC/Cy5) - a total of 13020 images. Video courtesy of James Marr, Leica Microsystems, USA

Developmental Biology Image Gallery

Developmental biology explores the development of complex organisms from the embryo to adulthood to understand in detail the origins of disease. This category of the gallery shows images about…

Images of a brain organoid derived from iPSCs acquired with a THUNDER Imager 3D Cell Culture. The cells were infected with the pAAV-hSyn-EGFP and pLX-hGFAP-mCherry virus. The image is the 36th plane cropped out of a 53 plane Z-stack volume. Shown are both the A) raw widefield image and B) the same image after Large Volume Computation Clearing (LVCC). Neurons are labeled in green and astrocytes in red.

“Brains-In-A-Dish” from Induced Pluripotent Stem Cells (iPSCs)

This article discusses the benefits of using the THUNDER technology for imaging inside 3D human cortical brain organoids. These organoids are derived from human induced pluripotent stem cells (iPSCs)…

Spheroid shown here as a maximum projection of the raw widefield image data (left) and THUNDER image after Instant Computational Clearing (right). The images are derived from approximately 60 µm Z stacks. Different stains (alpha actin and vimentin) are used to help identify the various cell types. Images courtesy of Sandra Grijalva, Wallace H. Coulter Department of Biomedical Engineering, Georgia Tech and Emory University, Atlanta, USA.

Developing Heart Pacemaker Cells from Cardiac Spheroids

During the last decade, 3D cell culture has been established as a more realistic model compared to classical 2D culture systems. Cells can develop into miniature 3D objects, so called spheroids, which…

Putting Dynamic Live Cell Data into the Ultrastructural Context

With workflow Coral Life, searching for a needle in the haystack is a thing of the past. Take advantage of correlative light and electron microscopy to identify directly the right cell at the right…

Electroporated nerve cells (green), specific neuronal markers (magenta) and cell nuclei (white), computational cleared.

Into the Third Dimension with "Wow Effect"- Observe Cells in 3D and Real-Time

Life is fast, especially for a cell. As a rule, cells should be examined under physiological conditions which are as close as possible to their natural environment. New technologies offer tremendous…

Lung organoid taken at the "liquid-air interface" with a THUNDER Imager 3D Cell Culture. The cells originate from transgenic mice, so that the different fluorescence represents the degree of differentiation of the respective cell (superposition). The image acquisition was performed on day 21 after the start of the culture. Reference: P. Kanrai, MPI-HLR Bad Nauheim.

Observing 3D Cell Cultures During Development

3D cell cultures, such as organoids and spheroids, give insights into cells and their interactions with their microenvironment. These 3D cell cultures are playing an increasingly important role for…
