Physico-chemical mobility of cells in three dimensions is dependent on the development of filipodia, which is the fundamental instinct for survival and other cellular functions in live cells. Specifically, our present research paper describes the synthesis of 3-Mercaptopropoinc acid (MPA) capped CdSe/ZnS quantum dots (QDs), which are biocompatible and utilized for cellular bioimaging applications. Using the pancreatic cell lines BXCP3 cells, we successfully demonstrated the applicability of MPA-capped QDs for intercellular filopodia imaging. Employing these QDs, we examined the dynamics of filopodia formation in real-time along the Z-axis by using confocal laser microscopy.

A first morphological and electrophysiological characterization of Fañanas cells of the mouse cerebellum.

Fañanas cells (FCs) are cerebellar glia of unknown function. First described more than a century ago, they have been almost absent from the scientific literature ever since. Here, we combined whole-cell, patch clamp recordings, near-UV laser photolysis, dye-loading and confocal imaging for a first characterization of FCs in terms of their morphology, electrophysiology and glutamate-evoked currents.

High-throughput measurement of cellular traction forces at the nanoscale remains a significant challenge in mechanobiology, limiting our understanding of how cells interact with their microenvironment. Here, we present a novel technique for fabricating protein nanopatterns in standard multiwell microplate formats (96/384-wells), enabling the high-throughput quantification of cellular forces using DNA tension gauge tethers (TGTs) amplified by CRISPR-Cas12a. Our method employs sparse colloidal lithography to create nanopatterned surfaces with feature sizes ranging from sub 100 to 800 nm on transparent, planar, and fully PEGylated substrates.

The mechanisms through which polysaccharide (LTP) induces autophagy, however, remain largely unexplored. This study aims to elucidate the role of LTP in autophagy induction and its efficacy in mitigating inflammation within macrophages.

Background: Bacteria in physiological environments can generate mineralizing biofilms, which are associated with diseases like periodontitis or kidney stones. Modelling complex environments presents a challenge for the study of mineralization in biofilms. Here, we developed an experimental setup which could be applied to study the fundamental principles behind biofilm mineralization on rigid substrates, using a model organism and in a tailored bioreactor that mimics a humid environment.
