Here we describe a quick and simple method to measure cell stiffness. The general principle of this approach is to measure membrane deformation in response to well-defined negative pressure applied through a micropipette to the cell surface. This method provides a powerful tool to study biomechanical properties of substrate-attached cells.

FAQs
A pulled glass micropipette creates a fine contact point for selecting cells or small tissue regions under microscopic observation. When paired with a micromanipulator, it allows the operator to guide the pipette toward a specific target and apply controlled mechanical contact or suction. This combination improves spatial precision while helping limit disruption to nearby structures.
Mechanical contact can help separate or remove selected biological material, whereas suction can help capture and reposition it. Both actions are performed through the fine pipette while the sample remains under microscopic observation. Choosing between these interactions depends on whether the immediate goal is localized separation, removal, or movement of the targeted cells or tissue.
Spatial precision allows researchers to manipulate a selected cell or localized tissue region without broadly disturbing surrounding structures. This distinction matters when neighboring material may contribute different biological functions or developmental information. By preserving the surrounding context as much as possible, the technique supports closer examination of cell behavior, tissue organization, and localized developmental processes.
The workflow begins with microscopic visualization of the biological sample and preparation of a pulled glass micropipette. The pipette is positioned using a micromanipulator, brought to the selected cell or tissue region, and used with gentle mechanical contact or suction. The targeted material can then be isolated, removed, separated, or repositioned for subsequent biological examination.
Researchers may choose this approach when a study requires targeted manipulation of individual cells or small tissue regions rather than broad treatment of a sample. The method is relevant to embryology, developmental studies, cell isolation, and analysis of localized tissue regions. Its value is greatest when precise physical access and microscopic control are central to the experimental question.
After selected cells or tissue regions are manipulated, researchers can examine how cell behavior, tissue organization, or developmental processes relate to that localized material. In embryology and developmental biology, the ability to isolate or reposition specific regions supports investigation of spatial relationships within developing samples. The resulting observations connect targeted physical manipulation with biological structure and function.
