Summary
Mechanically induced calcium signals in endothelial cell networks are robust and consistently propagate, ensuring reliable cell-cell communication despite environmental changes. This highlights a key vascular signaling mechanism.
Area of Science:
- Biomedical Engineering
- Cell Biology
- Vascular Biology
Background:
- Vascular functions rely on calcium signaling regulated by mechanical and biochemical cues.
- Intercellular calcium communication needs to be resilient to microenvironmental variations.
Purpose of the Study:
- To investigate mechanically induced calcium wave propagation in confined endothelial cell networks.
- To determine the robustness of calcium signaling under mechanical stress and varying network architectures.
Main Methods:
- Utilized plasma lithography for geometric confinement of human umbilical vein endothelial cell networks.
- Applied single-cell level mechanical stimulation using capacitive force probes.
- Observed calcium wave propagation via fluorescence calcium imaging.
Main Results:
- Mechanically induced calcium signaling demonstrated dynamic regulation against diverse probing forces and repeated stimulations.
- Calcium waves consistently propagated across various dimensions (monolayers, cell chains) and topologies (linear patterns, cell junctions).
Conclusions:
- Endothelial cell networks exhibit robust calcium signaling essential for cell-cell communication.
- Calcium signaling provides a resilient mechanism for information transmission in complex vascular structures with varied microenvironmental inputs.

01:27Feedback Regulation of Calcium Concentration
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

01:19Contact-dependent Signaling
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

01:24Overview of Cell-Matrix Interactions
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
01:26Tension Response at Adherens Junctions
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.

01:13Cell-matrix's Response to Mechanical Forces
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:16Calmodulin-dependent Signaling
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
