This new method permits the simultaneous intracellular recording of a single adult mouse motoneuron and the measurement of the force produced by its muscle fibers. The combined investigation of the electrical and mechanical properties of motor units in normal and genetically modified animals is a breakthrough for the study of the neuromuscular system.

In this protocol a method to measure intracellular protein refolding after heat shock is described. This method can be used to study foldases like molecular chaperones and their co-factors or compounds able to influence their activity. Firefly luciferase activity is used as reporter to measure chaperone refolding activity.

We demonstrate how changes in the intracellular free calcium concentration and synaptic efficacy can be simultaneously monitored in a ganglion preparation of Aplysia. We image intracellular calcium using a fluorescent dye, Calcium Orange, and induce and monitor synaptic transmission with sharp (intracellular) electrodes.

Intermolecular Forces

Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen bonds, and dispersion...
FAQs
Load distribution depends on the complementary roles of actin, microtubules, and intermediate filaments. These cytoskeletal systems bear or redistribute forces across cellular regions rather than allowing stress to remain localized. Their coordinated interactions help connect force generation with changes in cell shape, internal organization, and the mechanical stability required for cellular behavior.
Molecular motors generate and move mechanical forces, while adhesion proteins provide connections that transmit tension between cellular compartments. Membrane-associated complexes and cell junctions extend these connections toward the cell boundary and neighboring structures. Together, these components create linked pathways through which force can influence both local cellular architecture and broader tissue organization.
Mechanosensing links a physical input to a biological response by allowing cells to detect changes in their mechanical environment. Studying this relationship helps explain how force becomes connected to cellular structure and behavior rather than remaining a purely physical event. This perspective is central to research on mechanotransduction, in which mechanical information influences cell function.
A useful analysis considers three connected stages: where force is generated, how it propagates through cytoskeletal and adhesion-linked structures, and how the cell senses it. Quantifying intracellular forces can then be related to changes in shape, migration, division, or organization. Separating these stages helps researchers identify whether a result reflects force production, transmission, or sensing.
Intracellular force transmission provides a framework for studying how cells maintain shape, migrate, and divide. It also helps researchers examine how individual cellular forces contribute to the organization of tissues. Comparing force-related changes with these behaviors can reveal how mechanical activity connects intracellular structures to larger-scale biological outcomes.
Mechanical force studies can connect cellular structure and behavior with developmental organization and disease-related changes. They also support research into mechanotransduction, therapeutic strategies, and biomimetic approaches. By quantifying forces and relating them to cellular or tissue outcomes, investigators can examine how altered mechanical interactions may affect biological organization without treating mechanics as separate from cell function.
