Cell-matrix Communication

Cell-matrix communication is the bidirectional exchange of mechanical and biochemical signals between cells and the extracellular matrix, a network that provides structural support and regulates tissue behavior. Cells sense matrix composition, stiffness, and organization through receptors such as integrins, which cluster into focal adhesions and connect extracellular cues to the actin cytoskeleton and intracellular signaling pathways. These signals influence cell adhesion, spreading, migration, proliferation, survival, and differentiation. In biology, studying cell-matrix communication helps explain tissue development, wound healing, cancer invasion, and fibrosis, while informing biomaterial design, regenerative medicine, and strategies for controlling abnormal cell behavior.

2019

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction. Types of Communication A common form of communication is visual. Visual communication can be...

Single-cell Microinjection for Cell Communication Analysis

Cited by 7 •

2017

We describe here how to perform a single-cell microinjection of Lucifer Yellow to visualize cellular communication via gap-junctions in living cells, and provide some useful tips. We expect that this paper will help everyone to evaluate the degree of cellular coupling due to functional gap junctions. Everything described here could be, in principle, adapted to other fluorescent dyes with molecular weight below 1,000 Daltons.

Here, we describe a three-dimensional culture method to analyze the morphology of primary breast cancer cells, as well as to study their direct/indirect interactions with monocytes and the outcomes such as collagen degradation, immune cell recruitment, cell invasion, and promotion of cancer-related inflammation.

Modeling Ovarian Cancer Communication for Imaging Mass Spectrometry Analysis: A Method to Identify Small Molecule Chemical Communicators in Metastatic Ovarian Tumor Development

This protocol describes a technique for sample preparation by co-culturing ovarian explants with the fallopian tube cancer cells. These samples are visualized using imaging mass spectroscopy, or IMS, to detect small molecule exchange between the cells and tissues leading to tumor development.

Contact-Dependent Cell Communication

2026

Contact-dependent cell communication, 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.Juxtacrine SignalingJuxtacrine signaling...
