Precise Spatial Proteomic Information in Tissues

Despite the availability of imaging-based and mass-spectrometry-based methods for spatial proteomics, a key challenge remains connecting images with single-cell-resolution protein abundance…

Cellular polarization dynamics before and after magneto-mechanical stimulation

Mechanically Stressed Cells under the Microscope

Traumatic brain injury, skin scarring, or fibrotic heart remodeling are examples for mechanical stress which cells and tissues are exposed to. In this article, the authors introduce a non-invasive,…

Normal skin imaged with Cell DIVE, 11 biomarkers shown.

Tumor MHC Expression and Intralesional IL2 Response in Melanoma

Genomics profiling and Cell DIVE multiplex imaging allows researchers to understand the immune cell phenotypes that most strongly predict response to IL2 immunotherapy in melanoma patients suffering…

Wt1b-positive myocardial cell adopting an epicardial cell morphology.

Wt1 Genes Can Induce a Cardiomyocyte to Epicardial-like Cell Fate Transition

From this study, it was concluded that Wt1 plays a yet undescribed role for cardiomyocyte differentiation by repressing chromatin opening at specific genomic loci and that sustained ectopic expression…

A Versatile Palette of Fluorescent Probes

Researchers at the Max Planck Institute for Medical Research in Heidelberg have developed a general strategy to synthesize live-cell compatible fluorogenic probes, and the result are the new MaP (Max…

Confocal imaging of a SARS-CoV-2-infected epithelia at 4 dpi (orthogonal sections)

STELLARIS Contributes to Understanding COVID-19 Infection

What are the structural and functional consequences of a SARS-CoV-2 infection? To answer this important question, the authors used 3D cultures that mimic an airway epithelium and used different…

STED Sheds Insight on Mitochondrial Protein Synthesis

In this paper the authors have adapted a click chemistry-based method coupled with stimulated emission depletion nanoscopy (STED) to address these questions reporting that, in human cells in culture,…

STED imaging of mitochondria revealed cristae dynamics during fusion. A comparison of confocal (left) and STED (right) imaging.

Mitochondrial Dynamics Quantitatively Revealed by STED Nanoscopy

Mitochondria are vital subcellular organelles, which can generate energy to support the entire lifecycle of biological cells. However, conventional fluorescence microscopy cannot provide a high enough…

Spectroscopic Evaluation of Red Blood Cells

Hemoglobinopathies are a major healthcare problem. This study presents a possible diagnostic tool for thalassemia which is based on confocal spectroscopy. This approach exploits spectral detection and…
